I think that generally TUSA- Tabata regs are some of the most underrated regs on the market.
I have a couple of them ( because you can buy them so cheap here), and I always liked to work on them. their components are excellent ( for me better than the ones of most other manufacturers), the performance is good.
I like especially their 1sts, even when they are often quite heavy.
To me the biggest problem is the availability of parts, Service Kits. There is almost nothing that you can interchange with parts from other manufacturers.
So you would need a TUSA Dealer around who can support you with that.
But if you should have access to TUSA parts, I would not hesitate to get me a TUSA Reg if the price is right, they are very long lasting and reliable, I serviced quite some of them, because a customer used them as fleet regs ( in the end he had to change for another brand, because he could not get parts anymore, don`t know why).
I`m not familiar with that particular model you mentioned, but I guess that the quality is still as god as the older models I know....
