Trent, if you haven't already done so, call the folks at Gun Dog Supply in MS, they can more then likely tell you when they'll be getting the first or any subsequent shipments of the new 320s....at least that's what they did for me when I ordered my 220 and collars last year....everything they told me came to pass exactly as they stated. Good luck bud.
Thanks Neal, im on a waiting list with buzzzardsroost right now... they seem to have the cheapest price i have found and ive done a good bit of buisness with them before.... theres only about 30 people in front of me, and im sure gundog has a good list.. but thanks for the info!!!
