If I do a less bulky-ish order I can manage to get 0.1% on all but 1R. (Simply because I can't FIND any 1R 0.1%)
But picking on the poor 1R only being 1% is mean since contact resistance is probably more then that.
The lineup would then be
Wishay Dale CRCW 1/4W, ±1%, ±100ppm/°C for 1R,
and
Yageo RT 1/4W, ±0.1%, ±25ppm/°C for 10R-100K
I'm only capable of buying these in 100 quantity at a time though. 1000 quantity would mean about $750 upfront for resistors alone and that's just too much for me.
Due to the limited number of sets I'd prefer to sell all 6 values per order to keep an even stock. When all resistors are sold I can order 100 new ones and repeat as long as there is demand.
That would add up to $12.60 for 54 resistors. (No spare to drop under the bench never to see again)
Plus ~$5.10 for the boards and ~$2 for shipping gives a total of ~US$19.7 delivered. (Actual switch not included)
