The bike I bought for £350 will get me to the same place just as fast, and including repairs and upgrades I've got about £600 in that bike. So for all I wouldn't want to lose that £600 bike (and wouldn't leave it unattended all day) if I used it to commute to work in London it would have paid for itself in a little over four months (probably more like three months now, as I don't suppose the monthly season ticket is any cheaper than it was then).

As to how much to spend I guess on a commuter bike that would depend on how far the commute was. If it's a couple of miles to the station to take the train from there then I'd agree with the idea of having something as cheap as possible, although for a couple of miles I'd probably walk it rather than faff around with a bike, locks, lights etc. If it's a longer commute I'd want to be doing it on a bike that was fast enough and comfortable enough that I'd get to work in a state to work rather than spend the first hour soothing the assorted pains from riding on a bike that wasn't really up to the job.

If the commute were long enough to want to do it on a decent bike but there was nowhere to adequately secure a bike at the other end I'd look for a different means of commuting.
