I think Lego's a different egg over Hasbro stuff iFett, so mentioning making a buck down the road isn't a horrible thing. Lego's are widely available, usually good sales... People have ample chanes at getting them usually, and it just happens to be one hobby that holds its value and then some.
I've even contemplated selling my SW Lego collection for a profit. I have like 5 B-Wings, 5 A-Wings, 3 Y-Wing/Vader TIE sets, 5 TIE Fighters... I quit collecting after the TIE Fighter came out at some point, but I still pick up a mini-fig set now and then just to get like the Hoth rebel or whatnot.
Love Legos, hate the price, wish I could afford to have a full set around of them though.
