If I was just going for guiding I agree with Luka, I'd get the ASI290MM mini autoguider. Its USB2 and is $200 cheaper !

Bintel has the ASI290MM mini listed at $399 but the ASI120MM (USB3) at $329. I'll shop around to see what's best. I'm imaging with the ASI120MC guiding as we speak and around every 60 seconds the damn thing loses sync. Luckily my focal length of 550mm is forgiving of rubbish tracking (and coincidentally rubbish polar alignment
).
