Changing the default currency

[John Bell <..hidden..>]

How easy is it to change the default currency of an existing installation?

I'm setting up LSMB for an Estonian company. At the moment, the accounts 
would be in Estonian Kroon (EEK). At some point in the next 2-3 years 
the national currency will change to the Euro.  The exchange rate of EEK 
is pegged to  the Euro which simplifies things a little. We also do our 
export pricing in Euro.

Which is easier:
a) Start off in EUR and live with a little hassle in the short term
or
b) Start off in EEK and switch when the national currency changes

My gut feeling would be (a)

any suggestions?

thanks
