By the time you add on the bed extension and leg stand you are over £2,000 and into Record Maxi1 territory.
I have done a lot of research Adam, and apart from the various clones of the Axminster you already mentioned there is nothing in your budget that comes close to meeting your spec.
Sadly they are all much less machine for your money than the CL3. You have a choice between variable speed and quality. Personally I would put quality first and put up with the minor irritation of belt changing but obviously that is entirely up to you.
Good luck with it whatever you decide.
