I've had that same one for a long time, and am pretty happy with it. But I would recommend shopping around and watching some reviews. Things may have changed.
One thing to consider is the light. I was never happy with the light on this scope, and instead use a different flexible desk lamp. Most of the ones mounted to the scope have pretty short stems, and can't be positioned to shine from the front, or very low to the side.
I've got the SM-4 7-45x, with LED ring light, 0.7x Barlow, rubber eye cups, and double-arm boom stand. Basically this[1] with some extra accessories. Works excellently, the newer design allows mounting the ring light easily (there's a grove it sits in).
