My home came wired with Cat5e and coax, and it all runs back to a corner of my basement. There, it goes into this Bell Atlantic box that's set into the wall between the studs. I've been ok with this box, but it's cramped and I'm starting to need to fit more into it than there's space for.

I want to replace this thing, but I can't really seem to find a good replacement, or I guess I'm not using the right terms. Here are my requirements:

• Must be in-wall. I'll never get my wife to sign off on something that protrudes into the room.
• At least 21" high. I don't want to patch the drywall and I need the space anyway. I don't care how high it is, I can always open up more wall.
• Preferably not too expensive. I did find a couple things that matched what I'm looking for, but I'm not willing to spend $400 on a bent piece of sheet metal with a door on it. I'm hoping for sub-$100.
• Oh, it needs to have a door.
• If possible, a way to affix an electrical box into it. My current enclosure has one so I'll want to replace it.

Where should I look?
