i personally would never buy anything electronic off of ebay.. not saying your going to get ripped off or whatever, but what if you have an issue with the item?? returns and the like can be a nightmare from what i've read on here and a few other sites..
i was just reading a thread like two days ago on here where someone paid over $2k for some led lights off an ebay "store" which in fact turns out to be some guys house in the woods in maine.. he had a problem with the lamps, shocker there, and when he contacted the seller, a nightmare ensued... he's still out his $2k, and doesn't have the lamps anymore either..
i would much rather take my business to a legit online store .. someone like htg supply, or any number of other legit co's that i know will be there for me if and when i have an issue with a product.. the extra money spent goes a long way for the peace of mind that i'm getting from buying from a reputable dealer.....
just my $.02 though..
