Hi
I looked into buying a drum sander and had the same issues with this end of the range where they all look similar just different colors and badges. When comparing look at the overall weight as that can give you an idea. I found that people had found some brands were better in respect of the table flatness and build quality, Triton being ok. Other brands are Clarke, Von Haus, Schepach, Rutlands and there are others. I decided to look at the next level up which boils down to Axminster or Record and again they obviously come out of the same factory and are in essence the same machine althought you get more drums with the Axmister and with Record they are extras.
