So £20 vs £4 for a 1m length of M8 rod from my local fixings merchant

But wait that's not the end of it.

I can make delrin nuts myself (about a quid each, therefore £3 in total)...I don't want to imagine how much the nuts are going to be for that rod.

then you'd likely have to get the rod machined to fit with your couplers. Then you'll likely need custom rod mounts (ouch)

I reckon you're looking at the guts of £200 ...vs £20 for the cheap ' dirty M8 threaded rod route!

Horses for courses, but I'd imagine most new to CNCs wouldn't want to spend that type of money on a hobby that might not even have longevity of interest!
