Welcome to the forum, TCS!
The OP only stayed around for a day and then left. His last activity was after TLS' post on getting the knobs that Rick suggested (although I can't say if he read that post). So, I don't think the OP is going to come back and let us know what ended up working.
There were a number of good suggestions in this thread, though. Just let us know if you need any more help after reading through it and checking out some of the products that were suggested.
