Non electro's were a plenty before the Electro market took off. Now its become affordable... or atleast half affordable to get an electro of some sort.
When it was all mechanical it was easier to match players in a tourney equipment wise. Now its gone electro and not as cheap as mechanical markers, it is a little hard to match your rival.
Being out-gunned is not necessarily a good thing, and speed seems to be everything these days. So i would try a tourney with your setup and see what needs to be changed / added to compete.
A hard question seen as its not standard to view the mechanical vs. electro side of things.
Give it a try or ask around some more.
Good Luck With Your Cocker Building.
