[Closed] S/H FS for around £800? Options

This is not a WTB, as I'm still looking down the back of the sofa, under the drivers seat, and going through old suit pockets.

I'm going to have somewhere around £800-900 to spend on a bike. I generally like to buy s/h as I like to get the most for my money.

I was originally wanting a Bird Zero, but the more I think about it, a FS should allow me to stay in the saddle a bit more.

So, what sort of decent FS bikes can I be looking at for around this price? Bonus points for small fancy/pretentious companies as opposed to the big names (I'm a brand cretin)
