With bee suits it's the old saying "you get what you pay for". It's up to you if you don't mind the bee stings etc. Good quality zipper, or rather a bad quality zipper will make you hate a bad suit. I've bought lots for me and others. I can't recall what I ever paid, and never will. I know it's different for me full time at it, but a bee sting is a bee sting and comfort is comfort. But a cheap zipper or poor quality mesh that you can't see through against the sunshine, or even thin cotton that in two washes gets even thiner, they are the things that really get to you later.
Bottom line.. pay as much as you can, touch and feel before you buy.
Good luck let us ALL know what you decide.
