Definitely my Canon ZR10 miniDV camera, it was the first thing I ever bought on ebay. I bought it right when it came out years ago for 500 bucks less than retail because the seller didn't have a reserve and spelled "Canon" - "Cannon", since it was mispelled there wasn't much exposure to the auction. :D

The best thing I ever sold was my '89 Mustang 5.0.:cool: Boy, do I miss that car, but I don't miss the speeding tickets! :eek:
 
I've made quite a few eBay purchases in my day, but my favorite recent purchase is my Apple Mac Classic II. Pretty nice machine!
 
eBay purchase

I got an external USB & FW400 caddy for my 250GB hdd. lovely.

My brother got a signed photo of Charisma Carpenter (Cordelia in Angel & Buffy)

:)
 
I've bought and sold a ton of stuff on eBay. My favorite item is hard to pin down. Maybe the "Sound Gizmo" (by Fundimensions) toy I recaptured from my 70s youth. Other than that i've had great luck in buying high-end camera lenses ($2000+) at nearly half price.
 
I collect toys so alot of cool things bought. An Astroboy toy for my three year old was a great purchase as well as an original Fisher Price cash register from the 70's. He slept with the Astroboy for three days. Some Urban Vinyl etc.
 
Signed (accompanied by pic of him signing it) Ozzie Smith Cardinals jersey. Even if the sig is fake, I don't really care - more sentimental than anything else. Actually, I didn't buy it - my wife got it for me as a present.

My best purchase....my blank Cards Road Majestic replica

Although, if I can ever snag a 1G iPod for a good price, that will become my best purchase.
 
A printers proofing copy of the artwork to Saint Etienne's Foxbase album for £10.
It was a present for a friend who's favourite band is St. Etienne.
She loved it!
 
Defintely a battery for my iPod mini for a mere €19. A DIY job it may have been but it still saved my €50-€60 odd on Apples price.
 
My set of four Marilyn Manson action figures, which are still MOC, but I think about taking them out and setting up a nice display at least once a month.
 
A "ruby" that cost me $3.59 and when I had it appraised turned out to be a color changing star sapphirre, it has a perfect star and changes from grey-purple to reddish purple, best thing its insured for $38,000.

But the airport card I got brand new for $6.99 ranks up there as one of my most useful things i got of ebay.
 
I bought all my Macs on eBay:

- iMac G3 333, a couple of years ago, initially as just a programming platform, but then it somehow became my main email and web browsing platform.
- iBook G3 700, less than a year ago, which has been perfect for having a portable UNIX command line, wireless Internet, watching divx TV episodes, and burning CDs, DVDs.
- PowerMac Dual G4 450, a year ago, that I got my girl friend, so she could have a decently safe platform for using MS Word, MSN, web browsing, email, playing mp3s, etc.

I've also gotten accessories like video adapter cables, keyboards, and some Mac games. I totally prefer my Macally iKey over the Apple keyboards.

But, I always buy OS X straight from Apple, not second hand.
