You do not say where you live. If it is near Columbus Ohio, I can help you make sure that your chisels are sharp.
Note that I have done a lot of work using some very cheap chisels

Watch the edge and you probably need to touch them up often. I have a hollow grind so it is easy to free hand them. So it is a quick jump to some stones and back in action. Also, note the Unicorn method mentioned above.
That said, you have to decide how much you are willing to deal with the sharpening issues. I like this set, but it is over $400 for five chisels.

OK, so you take it back a step and get the same set in O1 for $100 less (so $340)

Those Narex Richter Chisels are starting to look pretty good at $130

Tones things back a bit and you can get a set of four Narex chisels (1/4, 1/2, 3/4, and 1) for under $50

I think that the Stanley sweet heart chisels have an OK reputation. Set of 4 is about $100 and 8 about $165

Many people here like the Lie Nielsen chisels

With all that said, I obviously own a mixture. If you really want to replace your chisels, decide a few things:
How much are you willing to spend?
Do you want to replace them one at a time with your most used first, or just buy a large set?
What type of steel do you want? People argue if you should buy O1 or A2. I really like the PMV-11 steel. I hear nothing but good things about the Narex Richter chisels and their price is good.
I do have the Set of PM-V11 chisels. I also own some standard extra long Narex paring chisels. I own a set of Ashley Iles Mortise Chisels. I also own a set of misc chisels. It started with those really cheap chisels mentioned at the top. Then I inherited a bunch of misc chisels that seem to be old Stanley Sweetheart
chisels (but there are no markings on them). The point with this last part is that you can probably also get some old used chisels (vintage) as well.
Again, if you live near, you can give some of these a try.
