Ye, I saw both those kits on Hannants, though I can't work out why the 2 bladed kit is £2 cheaper than the 3 bladed.
I still have their SM 79 kit in the stash, and I am determined not to replace it with anything else. But I shouldn't be to harsh on them, its nice to see a British company doing well and without Airfix I might not be building models now. And I don't know how it is over there, but here, if you tell people you build plastic models, the first thing they think of is Airfix.
