I have a friend that owes me some $ and a possible solution is my accepting these in lieu of cash. They supposedly run great but need batteries which I have a nearly unused a pair of.
I intend to take them on their trailer to a pond and start them both up and check them out. The trailer is home made and would need a title to be legal, yours to deal w/.
More info and pics to come, as it looks, Best Offer over $1000, his loss, your gain. I'm not an aquatic type so the deal would be "running, as is". Pm interest.
