If you can get $100 for it sans fork I'd be shocked. Framesets are always going to be tougher to sell than complete bikes, especially lower end framesets. Once you take the fork off, it makes it even tougher. There was a guy around here trying to sell a steamroller frame, granted it didn't have a crank or bb, for $80. It took him damn near three months to sell it at that price. Problem is, again with lower end stuff, that once you take the time to price out even a budget build buying a complete new bike often time ends up being cheaper.

Also because the crown race for the headset isn't included, at least assuming that it's still on the fork, in all likelihood whoever buys the frame will have to have a new headset pressed in anyways. Sorry to be a downer but if you're looking for honest feedback there it is.
