Frame for Life! (Dolan, maybe)

hey all, just wanted to say thanks for the advice: here's my story....

i am a total newbie when it comes to single-speed bikes, although when i was cycling around town last year on my an old crappy mountain bike from back in the day, i mostly only used one gear. so, why not? i'm also sure that i'll be in london for the next year, and leaving cheap, so i think investing in a bike is a good idea transportation wise. my basic quandry was similar to wappingwarrior's: do i get a off-the-shelf bike like a fuji, langster, paddy wagon, etc, with the intention of working on it over the next year, or do i spend a bit more at the outset and get some kind of custom made bike.

anyway, went down to BLB yesterday to see what they had. gotta say they were really quite helpful and i testrode quite a few bikes. but then the friend who was with me spotted a really nice, blue ciocci (i think) that also rode extremely well and was about 750quid. we ended up discussing that bike for a bit and the girl working there suggested all these improvements - changing wheels and trims around, essentially making it look prettier. "if it looks like that, everyone on the street will turn their heads as you cycle past to see the bike!"

then i came back home and found this particular thread and made me realise that yes, i was being totally ripped off. glad i decided to sleep on it! and i'm back to my original dilemma:

• langster, with it's aluminium frame?
  
• kona paddy wagon - my impression is that this is a bit heavier and i wasn't taken with this bike, but i haven't been for a test ride
  
• fuji track bike - seemed like a nice ride when i tried at BLB, but i stupidly didn't note down what year/model it was: does anyone know what it was that i tried out?
  
• lemond filmore - this was also nice ride, but maybe i'm confusing it with the fuji?
  
  

i know there's a few others out there in the same price bracket, but i'm trying to cut down choices here, not increase them. i've decided that i 'm not gonna build a bike to start with as i want it now - to be riding - rather than a month or two when i've got my act together.

any advice truly appreciated,

thanks,
