I think it's a terrible idea.
1.) It's in Prague, so any difficulties at home it will be miles away.
2.) It's more expensive
3.) You will be dogged throughout your career by the fact you had to go to Prague and you just look like a failure regards getting into medical school
4.) There is always a risk that rules regarding foreign trained docs could be tightened
5.) The language issue
6.) The actual quality of teaching is questionable seeing as it is not regulated by the gmc
