I wouldn't pass up a FW at that price. Can you test it out and see if it bounces at its fastest? I have a FW but honestly haven't used it much. You can resell the FW or have it for easy portability at home or to classes and retreats.
But I'd probaby get the robust 185 for traveling for the reasons Macybaby explained. Besides, it's in excellent shape and has a case. Sounds like you have reservations about the FW. It's a really good price, but you'd have to spend some money getting it road-ready, correct?
