If Charliebikemonger's Surly chainring alone is £32, would this entire 32t/33t crankset at £35 + £6 p/p be a contender?

Those Truvativ cranks are 175mm, which can make for pedal strike unless you have a high BB.

Which you probably do on that Kona?
I think a few people have 175's and it's ok if you're freewheel. For a beginner bike they'll probably be fine Rick.

and look for some cheap Shimano Hollowtechs or similar.

Or TS posted a link way back <<< for some cranks on eBay that were about £20, 26t complete with bashgaurd. Margs and some others had them once but I can't remember who made them.
