RE: Which kit?
Both the Goldberg Extra 300 and the Goldberg Suhkoi 26 would be great kit choices for a satio 180. I had the suhkoi with a satio 150. I sold it becuase it was a little lacking in power and didn't want to buy a 180. (lacking in power meaning Torque Rolls were at 90% power) But it had enough power to do the IMAC Advance sequence.
My Dad had the Goldberg Extra 300 with a YS 120 on it. Great power and VERY smooth for it's size.
But are easy to build . . . and build light.
Good luck
