Gonna throw this in here, very tempting option for power meters!
150Euro gets you the kit, and then you use a 30mm BB with a pre-installed 24mm reducer to give you the space to fit the power meter components into the bike (or even wire it into the center of the crank spindle if you have some laparoscopic skills) and certainly takes the edge of the price tag. Hell, you can buy a drill press and the kit for the price of some of those cranks!

And I'll add this here

Build DIY power meter, but please dont

TL; DR Makes a stress point in a very important component
ITT @Cardy George has buyer's remorse.

Yeah, but even low carbon steel has about a 3,500kg/cm^3 shear strength.
The Shimano spindle failures I've seen invariably occur around the non-drive spindle arm spline interface. There's no doubt it creates a weaker point on the spindle, but whether or not that's a tangible weak point compared to the other bonds involved is hard to say. They do caution on the "drillium" and do note that the readings will go haywire on the power meter if there's a fatigue fracture forming, so the main concern is a catastrophic failure...and I'd bet it will fail on the non-drive arm well before it fails on a 2mm hole should such forces be achieved.

Still, I think the potential market is pretty small, but it piqued my interest.

Lol, no. I actually saw the Cycling Tips article before anything else. It piqued my interest too!
