I'm in the same boat, and have done a ton of research on what/when to buy used against new. I'm thinking everything apart from the wetsuit and boots would be used. I recently bought an old Aladin tec 2G computer in excellent condition, and with only 42 registered dives for around 40 US. The women had ceased diving for quite some time and just wanted to clean up. It doesn't lock you out if you happen to exceed your No Decompression Limits. Which I'm not planning on doing...
I was lucky to have found a great starter kit of good used BCD’s two for me and one for my son, 2 tanks (in hydro and Vis now) fins, weight belts, one Scuba Pro Mk20 1st stage with G250 2nd stage regs.
Found a brand new 3mm wetsuit today locally, still with the tags on for $25 along with brand new boots my size.
Trying to get two people together is very expensive along with getting my 13y/o son certified. Normally I’d buy new, and one piece at a time, just not in the budget right now. So buying second hand and traveling to gather the items is the only way I can afford to do it for this summer.
But the thrill of the hunt and learning all the newest tech has been very fun itself.
I can’t wait to make some memories with my son this summer. The day after he gets certified and I take my refresher course we are headed on a get away to four of our local Texas rivers/lakes to dive for two weeks. My absence from diving was due to not having a dive buddy, which I seem to have finally solved.
Now to find a good SP reg for myself and we will be all set, can’t wait to see what adventures await, happy diving buddy, hope you can find something for yourself. And enjoy the journey!
