Look on second hand sites, that's where the serious deals are to be had.
I bought mine from Office Clearance Warehouse.
I went to visit their warehouse in Swindon, it's a very small business they run but they have a huge amount of stock and were really helpful. They even delivered down to Cornwall for free :\
They have a great deal there for £79.99, looks like almost exactly what you're looking for. They may come very slightly marked through standard wear and tear, mine had some to the underside of the desktop, but it's something you never ever see![]()
Seeing one for £99 excl. vat. What's the other one you're seeing?

As long as I won't visibly see it, they can mark the bottom all they want. That's really been my only concern buying used imo. I am WAY too OCD about any surface marks I can see.
