I knowJL makes one, and Wickedcas.com has one.....neither of them are below the 300 dollar range.

anyone have a cheaper one ?

 

I'm guessing not. That is a pretty fair price for the labor involved. The only way to do it cheaper is to spend about $100 and do it yourself. Lots of people here to help you. At $300 or more that is what I did. Plus I learned something usefull. I still haven't seen a mass produced enclosure like the one I wanted anyway so I didn't have a choice really. What is stopping you - the money only or the feeling that it shouldn't cost that much?
