This one is much recommended, I think it's available with or without the camera.

The Skywatcher guide scope looks a very neat solution.

I must be old fashioned; I can't see how it can guide effectively with such a short focal length. At that length 3.75μm pixels will span over 3arcsec of sky.  I know centroid calculation brings the accuracy up, but what accuracy of guiding are we expecting?  I'm certainly no expert on guiding, it just raises a few questions for me - I've obviously not tried one.

Ordered this one from 365Astronomy as the only one that can get it in a week from Europe all the others were quoting 3 to 4 weeks probably from China
