I'm in the same predicament. So 6 mths ago I just bought a cheap set of Winrun 19s from Neta tyres Brisbane to tied me over till I decide for under $600. They look like a Bridgestone tread and are excellent on road & on beach. I really noticed the change from my contis which still had a couple of mm to the wear mark on the front tyres. Much lighter steering and better road grip.
Otherwise RF10s get a reasonably good wrap.
