Welcome to the forum..
btw, you seem to give the notion that you don't want to spend an awful lot on a system/install. If that is so, stay away from pre-made boxes and go with custom boxes. There's SOOOO much info (even where to purchase the materials from) that you'd have no problem making a killer box.
If you still think you can't, well, there are members that are willing to build a box for near cost...
p.s. My advice, don't mention JL's..:p
