The Irwin/Marples are a decent cheap option, but beware… the 1/8” one is horrible. I have the set of 4 from 1/4” to 1” that are okay users, straight and well-ground though the steel is crappy. After I bought the 1/8” version, I found that it was a bent parallelogram instead of straight and square.

Or just buy one or two really nice chisels, like lee valley or lie nielsen. I use the 1/4” and 1/2” the vast majority of the time, since I cut small joinery like dovetails and smaller mortises.
