I am using this one and love the purple pink color. Don't like that I haven't figure out a way to put the alarm in a way that makes sense.

I recently bought the Polar FT4 too (although not in pink). It doesn't seem to have a feature where you can set the alarm to go off when you surpass a certain heart rate. I've read the full manual twice, and played around with the watch itself, and couldn't find any such setting. Major oversight! I'd avoid Polar, JAH
[Edit: 9/4/12]
On the FT4, under Training Settings, there is a menu for "Training Sounds," and the options are simply "On" or "Off." When Training Sounds are set to ON, and the watch is in training mode, the watch simply gives off a double chirp every 12 seconds -- apparently just to let you know that the watch is still on and still reading your HR. I've set my target range to start at 105 bpm, and have jogged in place and watched as my HR surpasses 105. No audible or visual cue...just the regular 12 second chirping.
This regular chirping at 12 second intervals is completely useless, and frankly, makes it so one cannot keep the sound on while doing ordinary daily tasks, as the chirping becomes too irritating.
[Further Edit - Solution]
OK, I found a work-around to this problem. The double chirp occurs only when you are outside of your "training zone." Once in the zone, it becomes silent. So you just need to shift your training zone waaaay down so that your AT is set at the
upper, not lower limit of the training zone.
For example, based on my age, height and weight, the watch automatically set my training zone as between 125 and 157 bpm. At first, I decreased the lower limit so that I would enter the training zone at 105. But this led to the problem described above where the watch chirped constantly unless I was above 105. (I didn't realize at first that the watch stopped chirping when I went above 105 because I never wanted to stay above 105 for more than a few seconds when I was testing it out.)
Anyway, the solution is to move your range down so that you'll be spending most of your daily time IN the training zone, and your upper limit is whatever you think your AT is. Now I have my training zone set to 60 - 105. It almost doesn't matter what the lower limits, as long as you set it to something so low that you'll rarely if ever fall below that limit so you don't have to be annoyed by the chirping.
Maybe this was an obvious solution that I should have seen all along, but I blame it on brain fog!
