The monitors you mentioned are no where near the size of the Suunto, and are in my opinion only slightly larger (and I emphasize only slightly) than the A3 that I have. I'd say you should go to your LBS or running store and compare them side by side. As for the Timex I never considered, nor looked at it and can't make that call.
You have also mentioned that cost is a concern. The "S" Series you are considering are certianly feature packed, but at a much higher cost! (For me the extra features could not justify the higher price).
