I'm pretty sure there aren't any funds available to non-EU students, at least that is the case in the UK. International students are either expected to have:
a) very rich families or
b) loans from their home country or
c) a rich sponsor.
As for RCSI specific teaching sytle and value for money, I'll leave that for someone who has been there to comment on.
I think transfers even within a country are quite rare (including UK->UK). If you want to go to a UK medical school, why not apply there directly?
For what it's worth, I believe the RCSI has an excellent reputation and I believe that it is used to dealing with international students, so you could always email/phone their administration directly to enquire about the funding available to you.
