I know a really good place (where our band has been for over 4 years). But depends on what "cheap" is
The location will be more into the Dallas area.... The only thing that I know is close to Plano (that I know if and worth it) is Musician's Exchange and Absolute. How much does your band have to spend per month? $100? $200? $300? It wont be free tho...
We have the largest room, as a five piece with a good size drum spread, and we pay approx $375. You wont find anywhere better than this place and there are cheaper rooms. Two story office/commerical building. Clean, dry, and everyone watchs each other's back (like a family). The owner doesn't like to have buisness signs ect ect... keeps the buisness as a "word of mouth".
He also has two hourly rated rooms, but I don't know how much it is an hour.
I don't have his number on me at this moment, but I have a show tonight and will be down there to pick up gear and can get it for you within the next few hours.
