I have had a Gyro SE for a little over 2 years now & I love it. I have recently upgraded to the orbe platter & VC power supply & these further enhance the performance. I can't comment on the other tables, but I have never had a desire to change tables & you always have the option to upgrade as I did. I found the Origin Live Rb 250 is a good arm match with this table, however it is not in the same league as the SME IV.
Hope this helps
Steve
