how to drive a yaesu G5500 rotor ?

[F1TJJ]

Hi all,

I'm going to buy a used Yaesu G5500, site/azimuth rotor.
I want to drive this rotor from my PC from Orbitron (using Wisp ?)
I've seen that several solutions are existing (Satdrive, Kansas City, UniTrac, FodTrack, Trackbox, ...) but I can't find what is the best solution or the cheapest one...
Moreover where can I find these interfaces ? or Any description to buiold one....


Thanks
