I got the Taurox as a Christmas present
I ordered the conversion kit from Victoria Miniatures in Australia -
linkIt comes in under the £15 UK customs limit, so I was't charged extra. p&p was a bit expensive, but not overly so and the stuff arrived in about 12 days - and that included New Year.
There's a lot of good stuff on that site, my biggest challenge was not buying extra things that would have taken the total over the customs limit
The main reason I went with that kit was to get the suspension side of things. Wheels were easy enough, but all the other gubbins looked more difficult to find.
