What is a good airsoft Pistol?

I am looking for a good airsoft pistol to use as a primary, I would like it at a decent price, around $100, good reliability, won't break easily, gas efficient, and good power. I would prefer C02 since I live in upstate NY, and propane doesn't work well up here in colder weather. I am looking at the G&G 1911 Xreme 45, but not sure.
