Verlinden make 4 different para sets in 120mm too, although they mey not all be in production you can usually tracke them down on the net. Dragon did a 1/16th scale para.
Also there is a british company called firing line
( http://www.djparkins.clara.net/fline/flmaster.htm) that do a couple of modern British soldiers with pack that could easily be painted to represent paras, just need to alter the cap badge if you choose the head with the beret.
Check out the Historex site listed above, there are many companies that make 54mm metal paras, Chota Sahib is one that springs to mind, and I think Historex stocks these.
