Definitely try some sizes before ordering, road bike sizing is quite critical.
Check for mudguard clearance & two bottle cage mounts – "pure" cross bikes may not have them.
The Jake is a old favourite but probably the least well specced of the four (steel fork). Personally I like the look of the Vapour but the Focus and the Fuji also look well specced for the money.
Dunno much about wheels, anyone with opinions on those?
Canti brakes on a crosser can be fiddly to set up, some have issues with vibration when there's a long cable drop below the front brake cable hanger (low mounted hanger on the Vapour is better). Or you can replace the cantis with mini-V's (but the purists will come after you with pitchforks!)
