Are there any rumors floating around about an update to the F75/T2 lineup? I've heard First Texas has been working on a multi-frequency detector but nothing concrete. Are there any plans on making them run with less chatter or anything else? Reason I'm asking, I'm thinking about getting a T2 but don't want to buy one and have a new and improved version come out a week later. Also, I know First Texas is real good about keeping their products up to date. I just figured I'd ask and see if anyone's heard anything. Thanks!
