eBay and bikes
I've bought lots of bike stuff on eBay (and lots of other stuff for that matter, as well). My experience has been that you generally get what you pay for, although if you are an educated buyer, you CAN find some very good deals on eBay.
I've gotten some real bargains on bike lights, tires, and an AirZound II bike horn.
Things to watch for:
-check feedback ratings. The seller should have at least SOME record and the feedback should never be lower than about 97% positives (and ideally it should be higher than that). Always check the most recent feedback as well since you can sometimes spot trends in poor behavior or changed behavior from a seller.
-check shipping charges. Unscrupulous sellers will pad their shipping charges to get more $ out of you. Small and lightweigt items shouldn't cost more than about $4 to ship, even when sent via Priority Mail.
-Does the seller accept payment via credit card or Paypal? It's a PITA to have to go get a money order (not to mention it costs you more $).
As far as buying a bike, I would be really hesitant to buy a bike without giving it a test drive first. You never know how it's going to fit you until you actually ride it. If you know the model number/style/size and have been able to give the bike up for auction a test drive in real life (eg. at your local bike shop or borrowed a friend's), then I think you can safely buy online. You might want to limit your searches to local sellers, to cut down on shipping costs. UPS charges about $50 to ship a partially disassembled bike.
Good luck--

Hey, if *I* can ride my bike every day in Chicago (rain, shine, winter, summer), dragging 100 lbs of kids in a bike trailer, then ANYONE can!!!!
