Thanks everyone for the suggestion. I guess I should have also mentioned that $400 was just the budget for the gun and I do plan on spending more on parts and mags later. I do not plan on gaming with it until I get a few more things for it yet, but do want something that will work out of the box so I cab better understand the internals.
It looks like I am leaning in favour of the WE right now. But I have heard that their mags leak. Can someone let me know if they fixed that yet?
