I agree that you can develop your own line of meat rabbits that do well on pasture and don't have diarrhea issues. I also know a couple who raise rabbits from Daniel Salatin's foundation stock and seem happy with them. I guess it's just a matter of preference.
On a different note, has anyone else encountered squeamishness around people buying rabbit meat? I was very surprised to find it where I live, but it seems like people just can't help but think of rabbits as fuzzy and cute...just pets. Funny - chickens start out fuzzy and cute, as do ducks, cattle, sheep, pigs - but those are ok to eat without reservation, apparently.
