For me, the killer "wireless simple cyclocomputer" is the Bontrager RIDEtime Elite, used in conjunction with ANT+ sensors for speed and cadence.
They are not super-cheap new, but I hunt for them on eBay to find new or gently-used ones.
The RIDEtime Elite has a configurable "scan list", so you have some flexibility for what is in the list when in "scan mode".
