The definitive OTP ( Off-The-Peg ) List (<£500 and <£1,000 sections)

Whoops, should also add that I've read a few older posts from this year, and it appears as though some people think that a decent SS bike can be had for £150 or so? Is this still possible?

Update: still haven't bought a bike yet. I've tested the Charge Plug and Charge Plug Freestyler (as fixed gear), as well as the Specialized Langster Monaco. The latter was too small, as I rode a 52cm one, and the riding position seemed really aggressive to me (plus i have chronic lower back problems), so I've asked to test a 54cm version. I really like the look too, but i'm afraid it'll be a magnet for thieves.

I haven't settled on it though, so I'd like to ask again for opinions. I'm looking for something OTP, as i don't have the know-how or the time to build my own bike. I want something SS, preferably with a flip-flop hub. I'd prefer an aluminium frame or at least a bike that weighs less than 20lbs. I prefer flat or riser bars, or at least drop bars with flat bar brake levers so i can switch if i want. I prefer having 2 brakes. I don't want a bike that's predominantly red.

I've considered the new Giant Bowery Mashup, but i don't like the bar end brake levers. The regular Bowery and Fuji Track have drop bars, which means buying bars and brake levers which I'll consider but prefer not to have to do. The Trek District looks ok, but it's belt drive and I have no idea if that's any good. The Trek Soho S looks decent, i have yet to test-ride it. I've also looked at the bikes offered by dani2kuk, they seem decent too.

Opinions again please, feel free to flame also (i know it's what you lot do best). :)
