I actually recommended to a friend who is just beginning his stringing journey the Alpha Revo 400 (table top version of the Alpha Axis Pro) and he is enjoying it so far. I personally use a prince neos crank and while the clamps needs to be replace its still a sturdy workhorse. I think if longevity & versatility are your main concerns then either machine would do. So if you think that the extra $450 isn’t worth it then you should get the Alpha Axis Pro which in my opinion is already nicer than my prince neos haha. I think the only thing that I should let you know is to make sure you get the full experience. In other word, make sure you get a dedicated customer service that can help you with troubleshooting. Either machine will last you a lifetime but the tension head and clamps will wear down; make sure beforehand to ask their solutions to these trouble because finding parts on the second-hand market will give you a tough time.
TLDR: alpha axis pro
