It never ceases to amaze me that someone can find SCUBAboard to make their first post to complain about an operation, yet somehow they couldn't quite figure out how to sign in and ask a few questions beforehand.
I'm just sayin' that's all.
Sounds like you didn't do your homework. If you'd have taken time to look into scuba diving in general, you'd have realized this is an odd case and probably should be avoided. Likewise, before dropping $8,000 - you didn't think to ask around if it was a good idea? Seems like there are many opinions and thoughts just itching to be told on this guy.
With that said, I do hope everything gets sorted out. That would be a harsh price to pay for such a lesson.
Obviously the OP has to take some culpability here...but it's worth keeping in mind that Rusty is a very convincing guy; I believe he has one of the most successful LDS's in SoCal. He gets you from every angle; he's experienced, knowledgable, somewhat charasmatic...but if those tactics don't work he has no problem morphing into: pushy, manipulative, intimidating, and condescending. The latter traits should be red flags, (and for me they were) but I definitely could see how someone could be lured in by Rusty...if you start out very trusting, you wouldn't even see the latter traits. I should point out that Rusty has been talked about online before and there are definitely people out there who like him...but I despise the guy, and everyone I have personally talked to (ranging from fellow divers to LDS owners) feels the same way.
When I was wanting to get OW certified, I was checking out various LDS's and I went to his shop; it was very impressive. Lots of high end gear, plus a cool clubhouse with a PS3 and HDTV...I thought I had found the shop I was going to get certified through. He sits me down asks me why I want to dive, have I snorkeled before, etc. Then here's basically how our conversation went:
him: we don't even use wetsuits here, you're gonna want to use a drysuit...we do all our dives in drysuits.
me: oh, using a drysuit sounds cool
him: Plus rebreather diving is really the way to go, so we let you try out a rebreather in the pool, and if you like it we'll get you trained on that (tone here sounds like the training is either included in the OW cert, or a small additional charge)
me: wow, sounds impressive, so how much do you charge for OW cert?
him: Anywhere you go charges you about the same for OW.
me: So how much do you charge?
him: Like I said, anywhere you go is gonna be the same...but we offer better quality here.
me: so how much do you charge?
him: all places are the same
me: well there's bound to be some variation from shop to shop...I've already encountered some differences in the shops I've been looking at, so I'm curious to know specifically how much you charge.
him: like I said, everywhere is the same.
me: okay...well that whole drysuit thing, is the rental included in the price of the OW cert?
him: no that's extra.
me: how much?
him: about a hundred dollars
me: and can I just put on a drysuit and be good to go, or is there stuff I need to know about it?
him: no, you'll need to know how to use it.
me: so is that knowledge provided in the OW cert or is there separate training invloved?
him: No, that is extra
me: So how much does that cost?
him: If money is an issue I offer private loans...you shouldn't worry about how much you're gonna spend, you should be concerned with the quality you're gonna recieve.
I could go on, but the point here is that he makes it sound like OW is the same price everywhere but he offers you a phenomenal experience for the same price. You have to cut through his sales pitch and start really asking questions before you realize he's trying to lure you in with the mentality that scuba diving cert isn't all that expensive, so that he can ultimiately talk you into spending thousands of dollars. It's tough to convey "tone" through text, but suffice it to say he didn't like all these questions I was asking and I could tell from his tone and body language that a lot of people simply do what he wants...he was trying to hide that he was hiding answers, but he was definitely intentionally hiding the answers I was looking for...or at least providing the absolute minimal amount information possible.
