The real issue, I think, Philip, is what is available to you in the UK. Buying one is the quick solution, but it might not be the best in the long run. A bench-top model might be most compatible with a small shop, but you might also consider building your own bench-top table around a plate system that suits your needs. (Note that shipping in a plate costs a lot less than shipping in an entire table.) Then, consider what sort of fence best suits your needs. The fence can be simple, or complex, commercial or shop-made. Either way, be sure that the bench-top table lends itself to being clamped to the bench in a convenient manner.
