Cherry ML relegendables mini GB

I'm trying to get my hands on a quantity of Cherry ML compatible Relegendable keycaps for my Cherry G84-4700 num pad.

The only company I have found who stock them (so far at least) is Signature plastics, but their cost is ridiculous (almost $4 a key for 20 keys) so unless you buy in pretty large bulk (i.e. way more keys than I need/want/can afford for this project) it is not cost effective.

Is there anyone else who has a need for these keys who might like to work up a mini GB with me?

I need at least 15 keys(aka sets), but I'd be more than willing to keep extras if it will bring me cost down lol.

20 sets $3.88 each
30 sets $2.69 each
40 sets $2.09 each
50 sets $1.74 each
100 sets $1.03 each
150 sets $0.79 each
200 sets $0.67 each
250 sets $0.60 each
500 sets $0.46 each

My preferred price point would be $0.79 or better.
