dave, I'm guesing you had a lot of request to check mirrors due to the HO mirror thread .I guess these folks dont realize they could build a tester cheaper then roundtrip shipping would be and that they arent hard to use. I made a tester over winter didnt even cost me $10 & using it was easy. it gave me something to do during the terrible feb/march we had here.
