What computer (not Garmin Zumo 590 type expensive - meaning VERY) works well with the recumbent trikes? I've got a Garmin vivoSmart that I use to monitor my steps, etc with and know it will interface with the Garmin computers. I'm leaning towards one of the Garmin Edge series - not sure if the 200 or 500. I'd like to have the Edge Touring or the 810.. but those are a little out of the range of what I am willing to pay for the type of riding we do (no real long rides or touring). I already have a Spot 3 for tracking where I go (and emergency help if I need it) that I got for a motorcycle trip. So basically I just need something good that interfaces with the vivoSmart and keeps tracks of metrics of distance, etc for my "fitness" stuff. Speed/Cadence sensor compatibility is pretty much required.
