never bought anything from eBay, just a point about accepting cash only. there's been some cases where paypal have been ripping sellers off, or a lot of these cases if you believe www.paypalsucks.com and www.paypalwarning.com. i don't believe everything i read in the net but there's pretty many pissed off sellers telling they never received their money...
so maybe there's a reason for some people to go "cash only"
