Pull up a chair and grab some popcorn, this is going to get good. A search of this forum will get you many replies to this very question.
Now for my comments
1. Typical E-bay seller "knows nothing about scuba stuff, just "selling it for a friend".
2. I have seen numerous SCUBA items on E-bay that were NOT SCUBA (SCBA Tanks and fire extinguishers for example) being sold as SCUBA on e-bay. When I told the seller, he said "I don't know anything about SCUBA" and continued to advertise it as SCUBA tanks.
3. Factor in the cost of all repairs being done with out warranty.
4. Factor in the cost of having the gear checked and serviced before use.
5. It is probably ok to buy used old stuff on e-bay. After all what is the worse that could happen? :dead: Anyway, funerals are inexpensive.
6. There are some good deals on E-bay. No doubt. But you need to be a savvy buyer and know the difference. I see stuff selling all the time on e-bay for more than my local shop charges for it new with warranty.
7. I just choose to buy my life support equipment at my local store, where I can touch it before I buy and touch the guy who sold it to me after the dive. Would I buy a camera or some other non-live support gear used, yes. But I would not buy my regulator, BC or wetsuit (tough to get a good fit) on e-bay.
