    I have scoured allelectronics, mouser, and digikey and haven't found a cheap large keypad yet. Anyone know where I can purchase a decent quality keypad with more than ~16 keys?

    Haha, I suppose you read my post too fast. There are plenty of 16 key keypads at my college, but I would like a much larger keypad. Such a pain to find one :(

    www.newark.com sells a keypad from Grayhill that has 20 keys in a 5 by 4 arrangment. Check it out here.

    You'd think they would have cheap keypads like the ones you can get on 5 dollar calculators. Ideally I would love to have something like this without the 80 dollar price tag.

    Short of having your own custom keypad designed, I think the great majority of the high-keycount keyboards generally available are 4x4.

    Have you considered placing two 4x4 keyboards side-by-side to double the key count? If you need more than an 8x4 then you can add more keypads until you have all the keys you need. If you purchase the self labeling versions, you can even label the keys to suit your applications.

    You're right hgmjr, the best thing I can do is just use multiple 4x4s.

    I like using ebay to find one-off things for projects, you can usually get a really great deal on some really high quality stuff. I once bought a 950$ motorized micrometer for a project for 50$, which was a steal :) And the list goes on :D

    I bet you can get an amazing keypad on ebay, or at least a good price on multiple 4X4s if you go that route.

    Thanks! Not a bad keyboard and a pretty good price too.

    Oh no, my secret is out, there will be 'bid-wars' over obscure electronic components now!
