I have found your review extremely helpful. I originally wanted to get the AV2500. But I found a good price for both of them on the internet (AV2500 at $92 and AV3100 at $118). Both price are below the retail of the AV2500 which is $149.99. Which one is easier to use? Which one is easier to program? If you had the choice which one will you get? I think I like the label feature of the AV3100...

Thanks for the input.
