I am not sure if you can get pressureless ball locally, try karom I think he may have lobang for Tretorn balls, I recall him asking if anyone wanted to buy these balls, please note, that this was quite a while ago, hopefully he can point you in the right direction.
I doubt you can score a US K6.1 tour for that much, I saw a advert on mudah.my, there is a US K6.1 tour but for RM550, feel free to contact seller to nego.
For the K pro 88.....I am not sure is this still available in local market in West Malaysia, both the rackets you are looking for are quite advance rackets lol, if you have the size to wield these clubs esp the Kpro 88...
I was about to mention that as well.....got ball machine, looking for premium ball, and looking for advance player's racket!
Later if you jadi go and give him some tips, in the end you kena tips instead x-p
walao eh, i am really low level la......go for heavy k6.1 and k pro 88 is because the star that own the racquet and the stability feel that small head size and heay racquet can give on one hand backhand. The micro x is more worth than normal pressurized ball in the ball machine if you do some counting lol...
