Hey Slick,
First of all, I apologize for not making it clear enough for you to follow - but in fact I was referring to the dozens, maybe hundreds of posts I've made in other threads recommending LeisurePro. Not the couple in this thread. Which I don't see as negative but in fact objective reality.
Second, let's break the rest of your comments.
In the rare event that the OP gets a defective product - or a recall is later issued during her warranty period - woouldn't it be a lot more convenient to go to her sons shop for a replacement/repair than sending it to Leisurepro? Admittedly chances are small but tell that to all the people who've been affected by scuba mfr's recalls. There's enough of them that we have a forum just for that at the top of our mfr's section.
And let's break down your "excellent deal".
The OP has stated that she plans to dive 10-15 more years. And previously used her Mares for about the same interval. Without knowing one assumes that since she recently had it in for service when they found the cracks etc. - she may have routinely done annual/bi-annual service in the past. As do most divers.
I don't think scuba mfr's just made up 1-2 year service intervals without some data on the damage salt water/moving part wear potentially does to rubber and other parts. I find it kind of curious that Atomic, SP, and Aqualung all have a 2 year suggested interval now - it would seem that marketing a 5 year interval would sell more regs if one of them could support it. On a $500-1500 purchase I doubt they care much that their dealer makes $60 every couple of years servicing it.
The Micron is $250 at LP. Its' $495 list - I read somewhere AL allows 10% wiggle room for the dealers. Since the OP's son is one, let's say he can do that - so say she can get it for $450. She's stated she might dive 10-15 years more.
Recently someone posted what they paid to have their Titans? serviced - itemized their bill here. IIRC the service kit was $32 from their Aqualung Dealer. So the OP would pay $180 for service kits regardless of who did the work - her local dealer or Leisurepro - over 6 services. Which you and I both know probably aren't necessary but a lot of divers do it.
$250+$180 is $430. For $20 MORE over the life of her reg she could have a warranty for the first two years. Plus there's sending it back to LP if it does need to be replaced - vs. asking her son to replace it locally. Read the recall notices in our forum. Most start with "return to your local dealer for service under this recall" or similar. And I assume AL will continue to offer the kits at $32 a decade from now - bump that $5 a few years from now and the "deal" is actually a slight loss.
I can't speak for you but that's worth $20 to me.
