I must admit i nearly bought through ebay.
I looked at mount gox.
then i looked at everything i had to do, and the wait and understand how to use new software and then read about the how careful i have to be.
And i know ebay, i'm comfortable with ebay and i've used it for years.

if it had been closer to the exchange rate i would have bought it (not from this guy though).

but then i would have found i'd need the software anyway... and so on.
