im looking for a computer that measures both cadence and heart rate accurately, but i do not need or want to spend more on a gps computer. im a bit wary of all the different computers because many of them have mixed reviews. any suggestions? thanks

I just ordered an sigma Rox 6.0, still on the way

Polar

Cateye CC-RD430DW Strada Digital Wireless

Sigma Rox 5.0 I believe

If you ride with a smartphone that is BTLE or ANT+ capable, consider getting sensors that your phone can receive and record. My Galaxy S4 receives both, but I continue to use my old Garmins anyway.

I just bought this one recently. It seems to update REALLY slowly...it still shows non-zero speed and cadence values for at least three or four seconds after the bike comes to a stop. Sensors and magnets are all well within specified ranges--maybe a defective unit?

If it's only 3-4 seconds everything is OK. That isn't bad for a small wireless system like that. I have the model that doesn't include the heart and cadence but it does have a 3-4 second delay.

My Bontrager wireless computer is much faster, but at least it's good to know that the delay is to be expected. It doesn't bother me much during riding; just seemed a little odd.

Over the years, I've found that one of the best features of such a device is the ability to upload to computer software. Then you have a record of everything you do on the bike. If you get a multisport wrist watch type device, you can have a record of your gym work, hikes, walks, everything. I find that very valuable, not just in the near future, but over the years. I use a Polar device and upload data to Polar software and also to TrainingPeaks. A TP Premium account gives you access to excellent training tools, a huge upgrade to a mere HRM. The Polar RCX3 is about equivalent to the older unit I've been using. I know, doesn't meet the "cheap" criteria, but if you're actually training it's a good deal.

what exactly are the difference between these? besides one being 5.0 and other being 6.0

never mind, it seems that the 6.0 has altitude even if its the same price

If you're spending $116 + tax on that, why not get the $150 Garmin Edge 500?

the 116 includes the heart rate strap and cadence sensor
