Reply to knobs for akai mpd26

looking to replace the knobs on my akai mpd26, but cant find any info on sizes. mpcstuff has some nice buttons, but they have a line on them to show the relative value. the knobs on the mpd26 are continuous turn, so id love to not have a line randomly there.

any ideas? im also looking for faders as well, but those are an easier find. as far as style im looking for something colorful, a bit tall, maybe something that glows in the dark for visibility.

thanks!
