I currently own and use a Peavey Grind 4 as my main instrument. It's a great instrument for the price and could not be happier with it. I'm always tampering with setups and trying to achieve setup for my tastes. When it comes to action how low is low action? I don't have any feeler gauges but I'd like to know if what I have setup is pretty average or if I'm trying to achieve unrealistic string height. In the pics attached is about the lowest I can go with and I have very little fret buzz. I can just barely slide a CD under the E string at the last fret without it pushing the string up.
