I've got several of those 77OTs and they are great knives. Been using one for many, many years, it sits on the kitchen window sill above the sink, always ready to do some tiny touch up on a piece of venison or a bad spot on a vegetable.
I reckon the one for $37 might be okay if you really need one, especially since it's a real one and the other one...?
