Greetings and welcome to the forum!
I'm all about sets that can get into play as well but to answer your question about what a good starter set would be would really depend on several things.
1. Whats your preference when it comes to chips? There's quite a wide range to pick from. There are china clays, china ceramics, other ceramics, plastic, Paulson, BCC, ASM, TRK and CPC. The chips named after plastics are a variety of US made clay chips, some older and no longer around but Paulson are the chips you see at many casinos in the past and present.
2. What's your set size need? What stakes are you playing and how large a game do you spread?
3. What's your budget? Depending on your preference, set size need and your budget we can narrow it down pretty quickly I think. Also is your long term goal to get one good set and call it a day or were you also considering collecting sets which you could rotate? This can get expensive rather quickly but the nice thing is the chips don't generally lose value depending on what you get and at what price.
Something you will hear us say often here is get samples! Getting a sample set of the chips to handle and evaluate before you make the big purchase is very highly recommended.
