Have two Cannondale Topstones I need to get power meters on as cheap as possible. Decided to use them for training on year round.

They come with FSA Tempo chainsets and I've seen some 4iii 105 5800 power meters really cheap at £200 each. Think they're reduced so low because it's the silver colour which doesn't bother me that much. Just need to get the cost down.

Any way to fix the 105 arm onto the chainset? Or should I just suck it up and change the whole chainset to something shimano that has adventure 46/30 rings?

Possible problems I see with changing to a shimano chainset is the FSA cartridge bottom bracket.

They’re not compatible, the FSA is square taper and 105 is Hollowtech 2.
