Sure, I got about halfway through the 42 pack on Sunday. Apart from being fiddley and time consuming to make they're also rather small for 1:32 setups, about 4.5cm high, so perhaps could be used for a younger crop. Fragile too.
The other type (http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=250619602536&ssPageName=STRK:MEWNX:IT) looks more rigid and is closer to the right size at 9cm, but the most you can buy are 16 a pack at about £12-£15 each
