I've recently bought a Carrera Subway One from Halfords. They are £300 but in the sale at £220. If you reserve online you get 10% extra off, so £198. AND you get a £20 accessories voucher which I spent on mudguards.
Now I like Konas, but they are way overpriced. The Subway is better specced than the Kona and a lot cheaper.
Mine is the new 09 model which looses the crappy suspension seatpost and adjustble stem, and looks quite smart in gloss black with subtle graphics.
There's not much needs changing either. Even the saddle, tyres and pedals are decent. It's a bit undergeared but 7sp kit is dirt cheap if you feel like adding some speed like I did (28/38/48 Crankset, BB & front mech to suit and 11-28 cassette for a tad over £50!!)
It's a nice ride too. Solid and comfy but quick and nimble too. I like it a lot, TBH.
Also, try looking at The Edinburgh Bicycle Co-Op Revolution range. Very nice bikes as well…. But some of them don't have braze ons for a front mech, which is why I bought the Carerra 🙂
