i like to have cadence, speed and distance functions. The old Cateye Astrale had those functions, and I think there is a model called Strada that also has those. But even more than those, I like the mid-level Sigma products. Mine are called "1602," but that is an old model designation. I would suggest just looking on the Sigma site, look through the feature lists, and then shop the LBS's and discounters for price. I can't say they are less than $60, but I think you can find a good buy. For such simple units, there's nothing wrong with shopping old stock, either.
I like to have heart rate as well, but that really pumps the $$. I've been using a Polar HRM along with the Sigma or Cateye. At present I'm interested in a more capable one, but I have a little job problem to fix first.
Dfrost is right - this does not belong here, but it's a simple issue to render assistance on. And if the mods move it to Electronics, you'll still have our responses.
