Hi Andy, I also bought a Collomix CX40 last year! Did you get it from Milcot Tools in Chelmsford? I was going to get the cheaper CX10 but the bloke in Milcot told me that some plasterers find it a bit underpowered and buy the bigger paddles designed for the CX40 or CX60 and end up straining the motor! Apparently the CX40 is also good for mixing up screed or small batches of sand/cement render which the CX10 can't do. The CX40's got the negative paddle which apparently mixes the plaster more consistently than the positive paddles. Being a non-professional plasterer I reckon it'll last the rest of my life ;D Love the funky blue colour too!
