Oh for Pete's sake...
Would y'all do yourselves a favor and at least check out the Profile systems? They really ARE the best bang for the buck (I wouldn't recommend 'em if they weren't), and what's more the president of the company has jumped into this thread and can answer all your questions about it.
Just in case you're wondering, I have NO vested interest in 'em whatever. I've known Dennis for more than 10 years and know he's good people who make a good product and stands behind it 110%. And these days, that's HARD to find!
