I think the best system is the KR8. Wonderful 2 pc system. No messy carts to refill etc. But if you want the best of both worlds. Keep this system first. learn its ins and outs.. and then keep another system as back up...like the joye 510 or other...if you would really need it. As a new purchaser if you would arm yourself with a KR8 system...you would have little call to go else where...
