this guy selling the standard driveshaft with gears and bearings £4.25 and £2.43 p&p sometimes has the sc in stock
http://cgi.ebay.co.uk/New-DuraTrax-V...#ht_564wt_1139
he does sell the sc driveshaft and chassis but has none on the bay at the moment,
(i've purchased 4 from this guy and arrived in about a week....)
i purchased 4 x sc chassis from him at £7.90 each and £6 postage for the lot,
and 4 x sc driveshafts and gears at the same price as the swb ones above
he isnt selling any at the mo (chassis or shafts) but message him, you may come up trumps
