The other factor is that I'm a key masher. I just don't type lightly, particularly when I'm gaming - my brain refuses to accept that pressing W harder doesn't make me go faster, and my failure mode tends to be one of:
* switch breaks/wears out
* pcb stressed/flexed by my mashing causes traces or solder joints to loosen. Keys will only work sometimes, and sometimes end up putting out the wrong letter. Pushing hard on the misbehaving key will often make that one work but surrounding keys will start misbehaving. This has happened on a few keyboards!
It's a little wasteful, but for the cost of 1 good keyboard I've found out that I would have chosen the wrong layout and wrong switch type if I has sprung for a good one right away. I also learned I need a good key plate and maybe go with wire wrapping instead of a PCB for the switches.
