if f16s are available govt should bit the dust and go for one time big purchase..t129 and everything esle comes second, these windows dont open up again and again, however, only if it is subsidized(FMS) otherwise better to just get a less restrictive plateform..
a 2005-6 deal of 55 F16c/d with 36 new and 30 old would be great but i doubt USA will offer used EDA stock ones..their isnt much lobbying for used ones...as it more attractive for USA if another nations gets new ones..they even blocked the used ones to NATO alley Croatia to force them to buy new ones
