My price range is up to $1500. I need something that spits out fairly high speeds (cant find the speed for the Playmate) and has spin and oscillation. I would like your opinions on these machines. Silent Partner is the cheapest, Tennis Tutor seems reliable and a fairly good deal, and from what I've heard Playmates are great, but it is at the top of my price range. Any thoughts? Also, where do you reccomend buying one of these machines?
