I have several different sets, But I like the one Divinorum posted. I think it's important to have them in some sort of case. and once the hole saws start getting dull you can just get new saws at home depot. Cuz it doesn't matter how good the hole saws are, you're going to dull them and need replacements. they will fit the standard mandrels.
Lots of the standard hole saw kits out there include all the standard contractor sizes and not always all the common locksmith sizes.
