Well, I went for the Jet, which arrived on Wendesday evening. I don't expect to have time to use it before Santa goes back into hibernation, but I've unpacked it and set it up just to get it out of the house, and I must say it has a good quality feel to it - lots of weight, robust mountings etc.
ON the whole I have a good opinion of Jet kit - I'll let you all know how I get on with it in the New Year.
Thanks again for the advice, folks.
