...and who would like to try your hand at it yourself, i have found a good place to get the roco minitanks. the online stores tend to have high sh charges so i looked further. i found a nice person on ebay who sells these little trucks;
48vw or Rudolf Zerr @
rzerr@dccnet.com
he has a large stock, much more reasonable sh charges and has promply replied to several emails. i will be getting two trucks very soon (one in case i really f things up on the first one) so i can try my hand at making one of these little wonders.
