Is there a "numberpad" controller to use for INTV, Atari 5200, Coleco emulators?

Wondering the options for numberpad controllers to better play emulators with Intellivision, Atari 5200, and Colecovision.  Just playing them with a standard controller isnt the same and can be very cumbersome.  Wondering if there are any USB or controller converters out there that are reasonably priced and work well that would serve the purpose well for the games requiring the numberpad

I use one of these. It's USB which kind of makes it plug and play. If you look around there are about 3 or 4 different manufacturers that make them.
