I have been researching, and I found that Tri-troncs is the only one made in the USA. I think the one we want is the Sport Combo, any comments?

Pluses-rechargeable collar batt, no separate collar antenna, waterproof, 20 different levels, reasonable size remote (not like varrying a stick of firewood around)

Minuses- only 1/2 mile range and I didn't want to spend quite that much.
