I know the feeling, but my point is that if you count the expenses for chasing rarities (including ones that might be semi-wild at best) round the country for years, would it really amount to less than travelling to an entirely different region of the world for a relatively short, but much more productive, time?
Or, say, what's the point in trying to find Long-eared Owl in Britain (where it's apparently rare enough to warrant its breeding/roosting sites being kept a secret) when you can see easily it in e.g. Serbia and probably for less money, too? Heck, even in Germany it's quite common and not very difficult to see, at least by owl standards.
