Hey i just ordered 2 subs amp box and a deck off of ebay there is alot of registration and stuff but i think it is worth it to save a few bucks and you can easily compare shit on ebay so i like and i should be getting my stuff in at the end of the week i will post a message stating how happy i am about ebay just for you!
I've bought quite a bit of stuff of ebay, never had any problems and I've probably saved $1000 off retail prices.
Just this week I ordered an Optidrive 200.2 for 167, it's usually about 280 plus shipping from an on-line store. Also got a hold of the optidrive 1000.1D for $201 plus shipping. The cheapest I've seen it on-line is $350 plus shipping, most places sell it for 380.
