Yamaha makes excellent products and they're built to last. It may be worth your while to see if there are any used TRB 6's near you. One thing that should be noted. The scale is 35" and neck is quite wide. If you're accustomed to an Ibanez-type spacing, you will need some transition time to get used to the instrument. I know it's not always possible, but if it's within your access, try one before buying.
