I'm looking at purchasing a second BH for dedicated use on my Sky Tracker. FWIW, my current BH is an Arca Swiss BH1. Looking on Craigslist in my area the two BH's listed are available at approx. the same price, with the Markins going for $200 and the Acratech $175 and both appear to be in good/great shape . I'm looking to see if anyone has experience with either or both of these and could help steer me in one direction or the other. Let me know if you need any further info and thanks for your help.
