I would actually look at EU countries? Maybe if you feel like your country of origin is too much of a backwater, sure, look further, but as long as you are within EU, university courses come between 1k and 5k/semester? Which, even with the more expensive option, you are well below 60k. And - you probably are too off path for "I am going to pick school for the prestige credentials", you already have 8 years of SWE in your CV, it is fine if your uni will be something random in Europe that works under Bologna Process. So - focus on schools that seem to be teaching well - or possibly, if you have becomming an academic in your sights, ones that would support that well. Also, I have several friends in their 30's and 40's doing university courses targeted at working people - they have weekend courses every other weekend and otherwise self study. They will end up with proper diploma and everything.
