figure out the biggest diameter of bit you're likely to use and the metal and then figure out the rpm corresponding to that. That's critical I think. You'd probably fry a large hole saw on steel with many drill presses out there. Found that to be a limitation for mine.
Also, I'd want to have a chuck system that is on some sort of MT type of arrangement, easier to remove than some of the cheaper ones with the Jacobs tapers etc.
Putting some money in a good chuck is nice but you need a sound base for that.
And I'd figure out the actual accuracy I'd need most of the time and even check the runout of a bit or pin if you have a chance, some are pretty bad.
