Well thanks one and all for the advice. 
I'll be able to get high-grade stainless hardened without a problem. I'll be happy to hone cylinder bores too..
8/10 of the cylinders will be doing all their hard work in tension, so buckling stainless isn't such a worry, but burring up the surface is certainly a valid concern.
The problem is that Sweden has a population that would fail to fill London properly (around 2 million people short of London's population) and while there are benefits to that, the amount of people who want a cheap cylinder are few, and the competition between vendors is weak.... So far, all 3 cheapish cylinders I've bought here have been of terrible quality, and I've had to rebuild them all.
The very base model, shortest stroke, smallest bore, and with a pair of rattly spherical bearings at the ends will set me back around $230
By the time the stroke lengths I want are factored in, I'm staring a $3500 bill in the face. And from where I'm stood, that's one ugly bill.
I'll let you know how I get on sourcing materials, and I'll throw a CAD model up here before (if) I build anything so you guys can pour over it and spot any problems.
Thanks for your time!
A little footnote... with regards to it being Sweden and corrosion resistance being needed... It's actually pretty mild down here in the south, and salt isn't used on the roads. I have a friend who lives in Pennsylvania.... and every day I look at our weather forecast and look at his too.... I have snow-jealousy!
It is however fairly bleak and wet for 6 months or so...
