I'd loved to have used the cheaper version when I was grinding, but my mouth was too small for the OTC mouthguards. But my dentist did recommend I try them before paying to have one custom fit. So, I paid (well, my insurance paid) over $1,000 for a custom-made mouth guard many moons ago.
So, go for the Wal-Mart version unless you have a special need for a custom fit. If not, get one from the dentist. You don't necessarily need to go to the dentist that advertised them -- any decent dentist should be able to make you one.
