Has anyone ever purchased one of these boxs from these guys? Was it good quality? I have a RF 10" that i want to install in it. Thanks

I think that the price is a bit steep. Do a search in the for sale section here as you might find one cheaper. Or better yet, make one yourself if you have the time like I did.
