Do you really need a microscope?
How bout just a third hand with a good magnifier instead?
This is what I use:

Is has fairly good height (unlike cheaper third hands, which are too short for my liking), good magnifier, and even some LED's that can be powered by either batteries or an AC power adapter. And it'd only cost you 14 pounds (which is a huge difference in compare to the one you've mentioned!)
But they do have reasonably priced microscope's too if you insist on going that route:

Anyhow, DX has free world-wide shipping, and are very reputable.
Do note though that it can take 7-10 days until they ship some items (it depends on whether it's an MVP item or not really)
MVP means it's in stock, ready for delivery next day, if it's not in stock, then they have to order it from the supplier, which takes a few days.
