Sport dog is good for the price.
Dogtra is more expensive but great.
Tritronics is the best prolly, and most expensive.
DT is good.
I would go with Sportdog on a budget.
Keep in mind that the beeper is going to drive up the price of a $200 collar to 4 or 500 bucks. Just because...
Here's a pretty basic collar, DT quality at 300 bucks.. Not too bad.
