Cheapest DIP glue logic? Answered

I am looking to by some glue logic chips to prototype in so they must be in dip packages. I also want them to be cmos chips and not ttl. I am looking for which family of logic is the cheapest and for a good place to by them on the cheap. I don't care about the specs that much in terms of speed by I would hope for 5V and the ability to supply 15mA or more. The reason I am asking instead of finding the answers for myself is that I have already tried looking but there seem to be so many families that are very similar and I cant come to a conclusion. Ii was hoping that somebody who had some experience working with them would have some insight into me question.

Bog standard 4000 series is the most flexible for many uses.

Those do seem to have replaced the 7400-family TTL chips which used to be the standard proto/hobbyist parts.

They're better than 74 series, because they are more flexible, and you get some LSI functions in them.

Thanks

4000 series gets a bad rap for being slow doesn't it ? but it's wide range of operating voltages (3-15V) , its current drive and low power makes it unbeatable for a lot of jobs still.
