I don't know about sites selling tables/shelves specifically for magic props, but I've got my eye on buying mysef an aluminium flight case (search on Froogle for them), and Michael Ammar had a brilliant idea for a performance table... but I wouldn't want to give his secret away as he showed us at a lecture a couple monhts ago - it might be in one of his books or videos....
I didn't realise you were prepared to pay that kind of money... have a look at emagictricks.co.uk - they've got a few bits and pieces if you simply search for the word 'table.'
When I saw Paul Daniels last year, he used a very nice perfomance table/(could be) servante/carrying case all in one. Rather than clog up TM by posting a piccy here, if anyone wants a look-see, PM me with an email address and I'll send a copy as an attachment.
