I forget the price. Judging by the box fight at the end (and yes, there is an end, somewhere

) it seems to be an auction. I think the price (probably a reserve) was between US$2000 and US$3000. The whole site is quite amazing. I've seen lots priced as low as 500 and up to 15000 (that's US$, not Lira

)

If you want to look for the Hungarian lot, it is somewhere in the Eastern Europe section, but I forget where. Sorry, there are many Hungarian lots.
Have fun, but don't have mortgage papers handy when you look. Remember your family needs to eat this month
