Take your time to shop around unless you want to end up with lots of unused pipes laying around in the future. I'm fond of Peterson, and with their vast selection, you will most likely find what you're looking for with them.
If you're shopping at a B&M, remember looks aren't everything. Use a clean pipe cleaner to check the line up of the drill hole, especially on a bent billiard. A pipe can look amazing, but if it draws poorly or is a pain to clean, you won't be enjoying it for long.
Good luck. Shopping for a new pipe is always fun.
