Minifigs have a figure that might look like the Cushing version:http://www.miniaturefigurines.co.uk/images/catalogue/RSF%2008.jpg
I wasn't sure they still sold them. Don't think they have the licence any more, so that would mean they wouldn't be able to make new ones. Not sure what the law would be about selling ones they already had.
The story I heard was that in the run up to Nu-Who, an exclusive licence was given to Character Options and all exisiting licences were curtailed (including the rather nice range of 54mmmodels by Media Collectibles). It was said that BTD were allowed to sell off their existing stock but not manufacture any more. Fifteen years on they might be running out of stock....There must be some wriggle room there, as anyone else who had anything vaguely Who-ish stopped selling them when Warlord received the wargame figures licence.
