Might be worth it to just get a $500 go car until you find a GOOD WRX. Sure it'll be $1000ish after licensing the beater...but do you really want to pick up your tuner-daily driver that's supposed to last you a long time on an impulse? It would cut your WRX budget down a grand, but I think you'de make up for it with careful searching.
I just drove a beater for 3 long months while waiting to finish my baby, it just made it all that much more sweet to drive it after the wait.
