So is the verdict on the first GT-40 release a DUFFER? Should i steer clear of it and get the Tergal? I know they made some changes on the chassis. IS the Tergal version a better product than the gulf #9. Anyone who has both care to comment?Would like to know which is the better product if I am going to spend $70US on one of these models. Any advice would be great. Thanks in advance.
