Re: so I have regripped the clubs myself, but....Using the compressor method, you can practice with the same club and grip many times. "wax on, wax off"
Be careful though, if you're removing an old non-pliable grip, it will crack or "explode". Once split of course, a grip is useless.
If it will make you feel better, you can change the tape out when you regrip with this method. If you are using the proper sized grips for your shafts, AND the old tape is intact, there is really no need to re-tape. The tape is just used to slightly modify the grip diameter.
Take your time and practice first. When you get good at it, you can use the same grips on two different sets of clubs j/k. But you could!
