If you want one for MAME, check out the X-Arcade Tankstick. I haven't had a chance to use one personally, but I've heard a lot of good things. This one's for 2 players, has a trackball and side buttons (for pinball), so it covers basically everything. The downside is that it's expensive. But they sell additional adaptors for pretty much anything so you'd only ever really need the one stick.
