I'm probably not going to be of much help. There are so many distributors for MR products it's a hard subject to discuss. Some are great, some are substandard. Many offer what appears to be a better price than MR, but then make up the cost in shipping charges! I don't personally know of any distributors in the UK, but I figure there must be.
One warning: some of the dealers actually don't stock the product - they order it from MR only when THEY get an order! So the shipping is delayed significantly.
My direct dealings with MR were fine. When I ordered an item, it shipped out quickly - when I had a problem, they really worked to solve it. But I also know people who were disappointed in the customer service they got from them. I suppose you'll always find conflicting accounts.
So the one piece of advice I have would be to make sure whoever you order it from actually HAS the product in stock.
Good luck!

BTW, I have the Kermit and it is really nice. For something that is mass-produced, the quality is very high. I'm still trying to figure out how they got machine stitching to look so hand done!
