I think the reason you don't see too many models of the very late Mk Spits is related to the fact that they did not see combat in WW2, were not produced in large numbers, and were not used by as many nations as the earlier Spits. Quite honestly, you don't see too many models of the very early Spitfires either. Most everything seems to be either Mk.IX or Mk.XIV which were the quintessential Merlin and Griffon Spitfire Marks. I must agree with rrudytoo above concerning the CJM Spitfire kit, having had the displeasure of framing one up for a customer some years back. Unless they've improved it a whole bunch my advice would be to do your homework prior to making any decision to purchase.
