Well, I won't duplicate my big post over in the TG forum here, but I picked up 80 or so games including some really good stuff like Vasteel, DE II, Super Star Soldier etc for about $600. All told, after this deal, I'm only missing about twenty Hucards for the US set, and most of that is chud. I went from nothing to a 3/4 complete US set. Not bad at all!
The best deal of the bunch was DEII for $60, I think.
My rule of thumb is this though. Regardless of what the actual value is, if you really get a lot of enjoyment from something you buy, it doesn't really matter. $600 is a lot of money (thanks, tax return!), but I have an entire library of games I will be playing for years, and which I could turn around and sell for much more than twice what I paid. I had always wanted to get a TG again, and now I have everything I sold plus piles more. I don't regret the purchase at all.
Hell, it costs a heck of a lot less than the rims my friend bought for his truck!
