Ebay - To use or not to use, that is the question

Ebay - drug of choice for internet junkies the world over.

I am never, ever going to use it again.

The moment I refund the stupid sod who wants to return the PDA phone I sold him (on the condition he understood it was BROKEN and there were to be NO RETURNS), I am going to close my account.

Perhaps its just a people thing. I mean, the system seems to work pretty well (with the exception of the various holy pieces of toast and babies being sold). Firstly, I made the near fatal mistake of selling the Landrover rear seats we had for a measly $15 dollars (they are worth about $400 at least), because it didn't occur to me to put my reserve price up higher. Next I put the wrong paypal email address for a hockey stick I paid $27 to post interstate, and ended up not being paid anything at all (It took me two months to figure out nothing was ever going to happen). And, finally, I decided to sell a PDA I bought off my cousin. It worked, when I bought it, and gradually begun shutting itself down after shorter and shorter periods of time.
The sod who is going on my to-kill list has reportedly taken it to a phone technician who claims there's been water damage. The phone hadn't even been outside while under my ownership. Grrrr...

Let this be a lesson learned to all. Or rather, 2 lessons.
1. Ebay is to be only used in desperate, financially starved situations.
2. Never enter into any sort of business deal with friends or family.

Now, I could go on forever and ever and ever about the numerous business deals our family has conducted with others that have gone down the drain, for one reason or another - but really, I just wanted to point out that Ebay, in my unfortunate experience, is a waste of time and money unless you know 100% what you are doing.
