Jim is, naturally, right on!
Paul Sellers, professional cabinet maker and presenter, recommends Aldi's workzone or workforce ( I forget the brand) chisels for the severe budget. I picked up two sets of those Aldi chisels to use like blanks to reshape to my sizes for small dovetails and mortises, and now also inletting. You can't beat 4 assorted standard chisels in chromium vanadium steel for around 9$!
I like flexcut, I'm too lazy to change the handles much...
