Decent single sided pcb - where can I find a source?

If I don’t need 2 sided, I just etch the other side off completely. All the cheap blanks I can get are 2 sided.

Doing it at a board house you just pattern one side. But I don’t see the point to confining it to one side if having one made. Doesn’t cost a penny more, and it’s sure as hell easier to lay out most circuits 2 sided even if it’s just a handful of tracks on the top. Doing your own I can see reasons to keep it one sided. 2 sided always take a lot more work.
 
To my mind avoiding plated holes has the disadvantage that pads will lift much more easily. Plated holes make very solid mechanical fixings, not just electrical.

On my pcb it had a heatsink on top of the pcb so through holes might have shorted out on heatsink. Same with tracks on top layer.
