Best cyclocross bike under £1000 and other CX chat

Well the EVO4 is £500 RRP, and the CSix2 is £1000 RRP, so I'd expect to be something around £650 RRP, (or about £525 in the real world).

I've got the FiveT and desperately want a lighter alu frame for racing this winter. Doesn't seem to be anything worth upgrading to though, no-one makes a light alu frame with sensible cable routing without disc tabs (don't want).

I bought a EVO4 with Scandium tubing and managed to get a price drop from CRC to 400GBP but the very next day I found a Csix2 second hand with fork for 400 so sent the EVO4 back, having looked at the EVO4 it's a very high quality frame and weights next to nothing, highly recommended
