This is the best machine of the lot by here. Its a ritmo with a bit more power and more equipment. Thats the bargain right there. Its single phase so plugs in the mains.
Post the Videos of it len nobody knows what it is
The Putzmeister is a used one. Ritmos are about the same price. I think a 6 kva would be ok for Normal stuff. The only time you will need the 8 kva is for texturing with a big compressor. Then i dont think a 6 kva will be good enough.
