I have the Meade 1.25" flip mirror. I got this a few months back and tried it out, but did not think it helped much. These cost $150 new, but if you want to try one much cheaper I'm selling this one for $90. It is in excellent condition, but does have some scratches on the collar where screw tension holds the camera on (much like an eyepiece barrel gets). I have the original box and instructions with the 2 accessories it comes with.
I strongly prefer payment by Paypal, as it makes everything faster. I'll ship this item insured within the US at my cost.
