Curious to hear opinions on this potential change for me. I have a Neos 1000 purchased re-bulit from JC at tennis machines dot com, and I'll be getting about $100 less what I paid for the machine on trade on a new Neos 1500. I am using a Wise tension head on my Neos 1000. Would appreciate what folks have to say on this and aside from the specific machine, how about the prospect of 360 degree rotation and swivel clamps over lack of full rotation and glide bar clamps. Thanks in advance.
