WELCOME TO HEAD-FI!
Croc,
I don't know anything about roomtunes racks, and I don't know how much you want to spend, but I have owned quite a few racks over the years, and the only one that has made me happy is the one I had custom made for me. See, the problem is you never know what you are going to buy in the future. Get a rack custom made strictly for you. Make sure the width; depth, and height are much larger than you need. Also, make sure it is extremely sturdy, and has plenty of shelves. When I had my rack built I looked at a lot of the dimensions, and weight of a lot of different components to make sure no matter what I bought I would be covered. Good luck!
