Mongrel Miniatures, have a very extensive range of 80's soviets
Ratnik have much larger (in winter wear) russians for chechen fighting, probably not what you are looking for, but if so, then PM bungle (a LAF'er) as he has loads for sale.
Red Star and Mongrel are compatible, as are the Eureka (i've got all 3) - i'd say the Mongrel ones are the best of the lot.
