Joe,
I did the exact same thing, had a Rexxon , which was fine for 2 or 3 years then just went pop one day. motor shot, so a scrapper. Bought a Fox sliding saw same as you are considering from Rutlands and it much more versatile and has much better capacity than the Rexon, although a heavier unit to lug about,.
its a noisy beast as they all are with brush motors but cuts well. holds its setting and prefer it to the Rexon, although that was fine at the time.
The bed setttings are strange at first, for 90 and 45 degrees just a detent ball rather than a solid mechanical lock, but works well and no complaints. and its adjustable anyway via a sliding detent ring under the bed. Just dont bother with the laser though, if you cant use a pencil mark or a tape measure a laser is not going to make you more accurate
and add a small pad of mDF to the hold down clamp metal face plate, evostick some 80 grit paper to the clamping face and its very solid and reliable...... The wing extensions are better than the Rexon too, and the supplied blade is a good all rounder
I believe the Fox is cloned from a much more costly model of a Dewalt model
