crank length!

In the process of upgrading/building new bike and have decided to buy a new chainset. I have never really considered crank length, but on inspection of the cranks on my size 56 trek they are 170mm in length. I am 6'1 and have an inseam of 90cm, i think my legs are long for my height, according to the equation for proportionate crank length to inseam I should have cranks of 190! which is a bit barmy to say the least!
So this is a bit of revelation as I could have had an increase in power with a longer crank me thinks, but i've hit a problem. It seems that the chain sets that are in my price range, i.e ultegra etc. only seem to go up to 175, and even though I dont plan on a 190 crank length I would like to get a little closer like 177.5 or 180.
But these only seem to be available in dura-ace etc, which could cost me upwards of £150.
So is it worth me paying a good amount extra for a longer crank? Is the difference that great? do other people have crank lengths proportionate to their inseams?

At 5'7" I should be looking at a 170mm crank, but I want to change my older Campaq Veloce chainset for a compact.
Thing is there aren't many of the old kind about...
I did find one but it's got a 175mm crank.
Which got me thinking. Can 5mm really make that much of a difference?[8|]
Discuss!!
Treefrog sums it up when he says gearing is of a higher priority. I`d save me money, and ensure my cassette had the right gears for me
Hope that makes sense.
