The Wiz. It's got tons of great emulators and ports. Few people name this as a system for shmups, but it's great for them, thanks to it's abundance of emulators. With Temper, you can play Star Soldier. GPFce? Recca. PicoDrive? MUSHA. GPSP? Gradius Galaxies. And you can even play various Cave games, including DoDonPachi at full speed. It's also got ports of rRootate and NOIZ2SA. Of course, there are plenty of non-shmup games available too, like Doom, Super Mario Bros, Gunstar Heroes, etc. Costs about $180, but I think it's on sale at GP2X Store for $30 off.
