Most WE Tech's are not under 75 so good luck with finding a gun in your price range by this company. They are typically around the 100 area, but maybe you've found them cheaper somewhere.
Anyways, if you want to know how they are, the answer is decent. They are real gas hogs, and their performance is alright for the gas it takes. However, I would recommend you get a KWA Glock, they are excellent, have lightweight slides, and are extremely reliable.
Good luck
