My KJW 1911 (Model KP07) has been fantastic over the 1.5 years I've owned it. Goes for around $120 nowadays I believe. It's nearly indestructible, Co2 ready, accurate, decent size and weight, and the mags are single stack style yet they double stack the BBs, so they're slim yet they hold 26 rounds a piece, and enough gas to easily shoot through the entire mag plus some. If you're looking for full auto, can't go wrong with a KWA Mac 11. Only $140, 50rd mags (which it can blow through in barely 2 seconds on full auto), and super compact.
