Earlier in this thread someone mentioned that the unit price would go down if Hungary/SA bought more planes. Based on their economies, especially that of Hungary, don't be looking for them to buy any more jets. They can barely afford to put the ones they're purchasing into the air.
As for those who consider purchasing an SU-27, think of the maintenance costs and then decide if its still worth the purchase. Everyone always wants the best, but when you realise just how much support work goes into an airframe, it sometimes just doesn't make sense.
If people want multi role, why not start picking up F/A-18 C/D's from the US, Canada, Australia and Switzerland in the next 5-10 years? Good airframe, cheap, decent avionics packages and not that many hours on the frames...well, maybe not the US airframes...but you get what I mean.
