Talk to a local plumber–all the better if you know him already, and ask if you can purchase an older used toilet from him the next time he replaces one. I like old Norris , American Standard, or Briggs; but there’s lots of them out there with standard bolt holes, flush and float valve holes..your plumber will know. Any hardware store can provide you with new guts for $25 or so. Don’t be surprized if your water bill goes up though…
