Mark, give Bruce at NOVA a call - NOVA often have nearly new stuff for a good price.
They are very freindly and of course just down the road from you in Warkwick (off the A46 at the IBM turn).
I have had some good deals from them when I gave them a call.
They may even have some secondhand stuff
Or you could try secondhanddarkrooms - they too often have good used NOVA washers around - and they are only about 1hr away by car from Kenilworth so you can actualy see what you are buying
Good Luck
