hi, I'm also considering an EQ3 Pro or possibly an EQ5 Pro depending on what I can afford and find on the second hand market just over a month from now.
As mentioned above by people who have far more experience than I do, the HEQ5 seems to be the de facto choice, however they are very expensive.
As a total beginner myself and from advice from others from this forum, the eq3 or eq5 pro maybe good for you starting out if budget is a consideration, which it is for me.
There is an eq3 imaging thread on this forum so you can see what people are getting from this mount. It might help you make in making your decision. If you feel after trying AP is for you, you can always put more money in later. Hth. Greg
