Copper oil lines are very typical on Long Island as well. You can always have it replaced with new copper that has a vinyl coating on it or sleeve it with Seal Tite. (flexible electrical conduit)
Or if you have the space you can cover the oil line with something to protect it from someone stepping on it.
I'm with you on that Jeff, I'm already invested in the Makita 18V/36V line, but have not made the jump to their 5ah/6ah batteries yet. The Ego line looks like a good product and to be honest I wouldn't mind jumping into that battery platform to save some money.
Shit, just as I'm looking to invest in either the Makita 36 V , blower & trimmer, or the Ego 56V blower & trimmer, Milwaukee decides to screw with my head now....
I swung by my HD tonight and they were sold out of the Rodgid Miter saw stand ($99) & those M12 XC batteries like Big Mike picked up, they were down to $69, that's a steal. I hope they get more in soon.
