Quickest.....I would agree with that.
Cheapest.......I dont think so. I only had $480 is doing THREE remotes on mine.
Sure, prices have went up some......but the cost of one of those diverter valves are not any cheaper than a single remote valve. And the added quick couplers to hook it to the FEL is where some bucks are wrapped up.
I'd rather just buy a valve, and hard plumb it. It really isnt that much plumbing if you know where to tie into.
It only took purchasing 2 hoses ~$40 to hook up a valve, because I re-used the PB hose that went from the loader to manifold.
About $20 in adapters to make valve work
About $25 in hoses, $10 in adapters, and $40 in couplers to attach the couplers to the valve
So up to $135 plus the cost of your choice of valve and bracket. Gives you $350 to play with to find a valve (maybe $100-$150) and make a bracket. ANd in the end you have a TRUE remote and not some contraption off the loader. :2cents:
