their lineup has changed a lot in the last year or so. They now have a line of wrist watch size monitors that are better than anything they have offered to date and they are better by far. I run with the new 110 but they have also put out a 310 and 410 a believe that offer a lot of difference bells and whistles as the numbers gets bigger. My 110 is outstanding and I almost do not know how I ever ran without it. My only, and I mean only, complaint is that the running pace is not real time. It has about a 20-30 second lag which isnt bad but I believe the new 3 and 410 models have the real time pacing. The base price on these is around $200 for the 110 without heart rate and goes up from there. The price is worth it as this monitor can and will last you a very long time. They have internal batteries that are charged through USB so no worry about replacing batteries or anything.
