Just swapped from Guidescope to a Lumicon OAG 2". The unit is great - mine had the prism (or adpters) the wrong way round for some reason but it was easy to fix. One side is set for 2" focuser the other is T thread. The only issue I have is focusing the guide and main cameras together - there is some need for spacers to achieve this - in my case I had to move the imaging camera back about 1cm to be able to focus my guide cam (a QHY5) and my imaging cameras (DS-145M Ice and a Canon 20D) at the same time.

Other than that I am not finding any probs getting a guidestar so for anyway and the results are better than with the guidscope - I am getting rounds stars and tracking to +/1 1" or less now...no prblems with flexure anymore.
