I'm in the same boat. Didn't get onboard the Omnibus train until 2012, and it's the only OHC of X-Men I do not have. I also buy these to read and to not just sit on a shelf and collect dust. I've caught it a couple of times at local HPB's, but nothing less than $250.

Hopefully the reprint in Epic Format won't keep Marvel from reprinting this. OHC's are simply a superior and more enjoyable format.
