I just build a table for the RF30 - well I just painted it few hours ago with a single coat. Few more coats and it will be done. The table is "heavy duty" and I burned way too many electrodes making it (well over 100).
I am planning to CNC the machine.
Part of the reason it was so cheap is that it is a 1980s model with MT3 spindle and non original motor - motor is from a drill press. So some work will be needed. MT3 spindle is actually not a big deal at all - it is far more popular for these machines in Europe then R8 & China has plenty of stuff for it - heck I have MT3 collet holder for my lathe.
