If it come's down to the french brittany or the munsterlander, I'd be hard pressed to reccomend either. I see the munsterlander a couple time's and not impressed. The french brittany I've never seen but would guess it's more for show than field. Have judged a good number of brittany stake's in the past and a good bit of National Shoot To Retrieve and a french brittany has never even showed up! Gotta be a reason for that. If your serious about a dog to do what you want, your best to stick with a breed that has proven itself in at least some of the areas you want. After you lay out anywhere from $350 on up, especially $1000, if the dog doesn't work out, your pretty much stuck. Your wife and kid's will likely love it even if all it does is lay on the couch and lick itself. A dog will live, naturally, form about 10 yrs on. The truth is your wife and kid's will love one of the other breed's as well and then you',ve a better chance of getting what you want.
