I have been looking for a ball machine for a while now. I missed out on a Wilson Portable machine that was only a couple years old and was originally $1100 and sold for $500. They threw in about 8 cans of new balls too! Anyways, there is a Sam P4 machine that retails for $1800 and is listed at $750. It has remote and all the bells and whistles-oscillation, spin, up to 75mph, etc. On the other side is the option of getting a Silent Pro machine brand new for 699. Has spin, oscillation, up to 95 mph I think. What's are your thoughts? The Sam is $1800 because of remote and maybe some features I may not use. I would like a machine that is programmable, don't recall now if P4 is, I think it is. (have to check). So new with warrantee or used with every feature? Thanks! Also I would offer $650 for SAM machine.
