IMHO, even if you have no plans of using induction get one that is induction capable. #1 Induction is on the rise for popularity and capabilities. You may find yourself wanting to try it in the future, you don't want to have to be faced with replacing a bunch of cookware if that time ever comes. #2 Induction cookware, by it's very nature, needs a heavier bottom so induction cookware won't be super thin on the bottom.
That being said, I have a 12 qt stainless I bought when I bought my first home. I just remember needing a bigger stock pot than the one that came with the set of hand-me-downs my mon gave me. I went to Walmart and the only one that wasn't paper thin was a Tramontina Professional. It cost a bit more than the thin ones, but IIRC, it wasn't bad. About 12 years ago it was around $24. It has served me well, and while I didn't care one bit about it being induction capable then, now that I've remodeled my kitchen and put in an induction cooktop I'm sure glad it was capable bc all of our non-induction cookware had to be replaced.
Speaking of induction. Modern induction is mind-blowing!! I can boil water faster on my residential induction cooktop than a commercial gas range can. Instant heat changes and incredibly low low-heat levels...if you ever have the chance, at least check it out. I wanted gas until I tried induction.
