Hi Nobby,
The Kaces Porter size #7 is really the PERFECT case w/wheels for my PSR2000: snug (but not too tight either). I tested BOTH sizes 7 & 9 on my PSR2000, and although the Kaces chart recommends size 9, I definitely think #7 is a MUCH better fit. I KNOW you will be happy with the Kaces Porter. I certainly am. - Scott
