Anybody have any experience with this. I was about to buy a new transmitter for my archaic Polar Vantage XL (was a really nice HRM back in the day) but the transmitter costs $40 alone and I noticed I could get an SI-90 HM from Performance for $30. It won't store my heartrate every 6 seconds like my Polar will, but it records time in, above, and below the target zone, and it's a wireless computer to boot so my handlebar won't be as cluttered.

So, anybody have anything to say about this brand or model, good or bad?

I have a sports instruments HRM. It is very basic but it does a great job.

Someone PMed me to call Polar because they have a trade-in program. It's 20-30% off a new one when you send them your old one. That's a nice program, but I would be paying $80 to give up a $400 heart rate monitor (it can record your heart rate at 1, 6, and 10 second intervals iirc) for one with less functions. I'm leaning towards just getting a new transmitter so I can keep using the old one. They were very helpful in verifying that the current model transmitter will work with my old watch.

edit: everyone seems to be out of stock on the transmitter, so maybe I'll give the SI a try. If it sucks, I can always return it and buy the transmitter.

I have two Sports Instruments HRM's. No problems other than it's a bit tricky to open the watch to change batteries.
