Thanks so much guys. I really appreciate the kind words. I believe Artin stuff is now available in the UK, but I can't recall the name of the stockist. Visit www.slotcarworld.com (hope that's O.K. Nuro) and look under "Artin Dealers" and you should find the listing. It's a great and vastly underrated product, IMHO. My entire layout -- aside from pit road -- is Artin track.
Regarding the Artin R1 or standard curve, it is a little larger than a Scaley R1 curve. Most likely somewhere in between a Scaley R1 and R2. No problems whatsoever at this point with long wheelbase cars. The track works brilliantly. And, it's cheap!
Regarding the trees -- they're all hand-made from Woodland Scenics kits. I used a poly-fibre material, also made by Woodland Scenics, stretched over the tree armatures. I then shoot them with some diluted white glue and sprinkle on fine ground foam of different colors. There are about two pre-made trees on the layout, but the rest have been done by me.
Yes, I agree about the MRRC figures. They're hard to find here in the U.S. though. I'm still painting some of the figures from the first batch I bought. I'd really like to buy some of the SRA figures (we really need a distributor here) and I'm looking forward to Monogram's rerelease of their figures.
