I would buy 5 old wooden handles chisels cheap as you can by old Sheffield makers like Sorby etc. I'd get 5 sizes, 1/4", 3/8", 1/2", 3/4" and 1". Still 100s out there going cheap if you do some work on them. Get them sharp and working. If and when you need more modern steel in the future you can spend money when you know what you actually need.
