I'm pretty sure the stabs in this kit were damaged by a prior owner. I've never used a board this crappy (the space bar is basically unusable, and I had to bend the 2U for the left shift key to get it in). So even $10 properly working stabs will be a huge improvement. I'll look at TX and Cherry clip-ins though, thanks! (Like I said, I'm totally new to all of this; all I've done to date was swap switches / keycaps, either hotswappable or through soldering. Oh, and bridge wires when I borked a solder point. But I know nothing about foam or lube or stabiliziers or ...)
