I just got a lrider corolla 2 and like it pretty well. Seems kind of cheaply made for the price, but the built in airflow regulator is nice. My buddy has a k100 and its solid(like roll of quarters in your fist solid), but i dont like bottom buttons. The natural is also nice, but i dont like pinky buttons. These are all sub 100 buck mechs.
Ive heard nothing but praise from Atmizoo owners ive talkd to. Ill probably get a roller or dingo next when i get the fever for a newer, better mech.
If you like chasing unicorns and have a couple grand to blow, legend has it caravela's are nice. But, this is only legend.
