If you've got a Meijers in your area (since I don't know where you live), you might be able to find it for $20. Then again, I've only seen it one time at Meijers ever, and that was when I bought it...
It's basically a direct port of the other versions of the game, so if you've played those you know exactly what you're getting. The game CAN be glitchy - some people have reported their game's memory resetting or other problems; mine has only locked up twice - but Capcom was giving new copies out to replace the messed up ones.
If you like the other versions, you'll like this one.
