Hello Curt Fuqua,
We get what we pay for; please, do not go with cheap, which is by definition, poor quality.
Look at the NCCA list and pick what would meet your goals and needs. If you want to work for a gym, go there to ask what they prefer. Better yet, you may want to find the answer to that question by asking at different types of facilities to see what the general consensus is for your area.
