I dont have any opinion on that exact model, but Tri Tronics is the best brand that I have used and been around. I have one and two of my friends have them for our labs. They are the most user friendly.. come with great customer support and there warranty is top notch. Im not sure if its the cheapest but here you go Gun Dog Online
DoubleCK the one you mentioned is what I use. You can get cheaper brands but they are all not made in the USA. When I bought mine I surfed the net and found the lowest price.
I use a G3 trashbreaker.After all the junk I have tried, this is the real deal. I can get you a fair price on one from a guy back east. If you want his contact info just say the word.
Well heck, I've been considering a dog so I guess I will just let you do all the research for me CK. I was going to post pretty much this same question.
