the best price I found on the 320 is sears on line , they had it for 450 with one dc40 collar , 150 dollars cheaper than most places , my buddy had a 320 and I had a 220 , he loaded my dogs in his and when I lost them on the 220 he would pick them up a lot sooner than I would as we went to the last place they where so I upgraded to the 320
Where did you end up going to get your map?
