I like your white T-Rex Matt - easier to see in the dark. Mine came second hand so I didn't have to choose the color.
On a maintenance note, the focuser on the TSA will loosen over time but it's easy to adjust, being constructed according to the same principles as the cheaper rack and pinions. The grub screws on top of the focuser bear on a pressure plate and there are slides at the 4 & 8 o'clock positions.
The focuser tube on mine was loose/wobbly and wouldn't hold any weight but 1/16th turn on the 3 grub screws firmed it up. I used acetone to melt away the glue seal over the grub screws and cleaned up the hole with a small drill bit.
