I bought a mosquito brand new in the box for less than the LDS can get it for. 68 dives on it and still going strong.

I have an old Aeris I, I can't imagine it being slightly used if you had to replace the batteries. I have never replaced the batteries in mine and it has over 150 dives on it.crispix:I bought almost all of my gear brand-new at my LDS, but I bought my computer used on ebay: Aeris Atmos AI. I have zero regrets -- the computer was slightly used, exactly as advertised, and from a seller with good scuba feedback. I've used it on a dozen dives so far without a problem other than changing the battery (which is a snap on the Aeris computers). For half the price of a new Atmos AI, this was a no-brainer. I'm fully aware it is out of warranty, and it was an acceptable risk for me. One tip: be careful about which brands you will buy used on ebay -- a user-changeable battery seems to be a must-have feature on a used computer.

Brookieman10:I flooded my dive computer 2x changing a user replacable battery
Are you really sure you want my "slightly" used dive computer? Only 56 dives on it !![]()
Do your self a favor and check out scubatoys- buy a new computer in a box from a reputable dealer who has been around here. You won't have to worry about finding that fantastic deal and then worrying if it new, abused or what ever.
Just my 2 cents
Ebay for me is for stuff I can replace. Having to look for another computer on a holiday is not fun. Been there done that.
I've also bought 5 or 6 regulators from ebay. Some for pennies on the dollar. All work great.
Just my 2 cents
