I try to never pay more than $15 ($20 for an absolute must-have) for a PC game. However, having played AE, I'd probably pay US$50 for it if I knew I couldn't get it any other way.
Surfacing, keep in mind that AE came out 4 years ago. I don't know how long they keep "printing" games, but you can be sure that all copies of this game that will ever exist have already been in existence for at least 2 or 3 years. If you can't do mail order, you're going to need to scrounge places that have decent bargain bins or used games. We had a good store for that here in the US, but they've gone all console-oriented and don't devote a lot of space to older games anymore.
Maybe OWI will come out with an AO/AE "Gold pack"-type deal; there seems to be a big market for that kind of thing.
Anyway, good luck in your oddysee to find exoddus.
