If you can afford it, the Lifetime Membership. It's expensive, like $500, but its worth it if you plan on staying with USTA for the long run. It also saves you the trouble of having to repay for your dues because your membership expires in the middle of a season.
A long time ago they gave out a leather jacket with the lifetime membership. I wish I knew what happened to mine haha.
I rock the Tennis Warehouse 9 racket bag. It has enough room for lots of TP.
