While I generally agree with rrs1, I also believe (from my experience) that if you like a particular style, you will likely later regret "settling" for a different one. Also, if this one is pricey, be patient, another will come along eventually. GT-4 & GT-5 conversions are plentiful enough at least in the US and at fairly reasonable prices, though I can't speak for the extra costs you would incur to get one to Finland and registered there, just might be worth looking into further if you haven't already.
