I hate reading reviews for all the "best" cyclecomputers right now that tout navigation. Jebus, do they think we are all idiots who get lost all the time? When did GPS navigation become the benchmark for a good cyclecomputer?

I had an incident with AFIB last year, and have been a bit paranoid about keeping tabs on my heart rate. I have an 8 year old Sigma on one bike, and a brand new Cateye on the other, and BOTH are giving me intermittent problems. The Cateye is showing wildly different heart rates (70-95-110-68 BPM inside of a minute) and is always reading 20--30 BPM LOW vs manual count. The sigma is just old, I think--BOTH the heart rate and the speed sensor stop at the same time, almost like it is not getting any signals to the computer, and it will do this at random through the ride. I thought there might be EM interference but it would happen at different places at different times over the same course.

I got a Polar HRM strap, thinking that it would resolve the issue and found out it works with NEITHER bike computer. Sigh.

So. Fellow Forumers! What computer would you recommend that provides a GOOD SOLID HRM experience and does NOT cost 300 bucks? Thanks, I do know how to get back home-no need for GPS!!
