I can't try things out first without buying where I am either. Hence, deficit testing; essentially, buy to try. If I like them, great, if I don't, gotta either return or sell them off here on Head-Fi. Sounds to me like you're in the same position where you live as I am.
That's the only reason I've ended up writing so many reviews in the last 18 months - got to buy them to try them in my part of the UK, unfortunately!
