I tried all kinds of cheap options before shelling out the big bucks for a custom made guard. It's a night and day difference. The custom guards are ridiculously priced, but I cannot go back to OTC guards after having one.
There are much cheaper options you can do at home instead of relying on a dentist to overprice it. See my comment elsewhere.
