I have been using the Skyguider Pro for about a year and really like it. In my opinion, there is no need to buy an overpriced wedge in order to get good results with this mount.
While the stock wedge could definitely use some refinement, I've been able to get good polar alignment by loosening the locks just enough to turn the adjustment screws and still feel some resistance. After that, I don't touch the locks. In fact, the only time I touch the locks is if the temperature has changed significantly from the previous night causing the locks to become loose or tight.
At the focal length that these mounts are designed to operate, you don't really need perfect polar alignment. Get whichever one suits you and get out and take some pictures.
For reference, I usually shoot at 300-400mm with 3 minute exposures. I'm pretty sure I could expose longer if my skies permitted.
Clear skies!
