Which is better - look for big eprom, or try to make your work in small eprom ?

If you are only doing one project your entire life, and they will build millions of them from your perfect the first time software, then 2k is fine.

If you are doing many projects, then you only have to look for a big eprom once, learn how to use it, then you will have an easy time making many small projects that will not be made in the millions. But if they are, then it would be worth the time to redo the software for a small eprom, right ?
