Hi there! I've moved to a scope with a longer focal length, and would like to swap my 3x barlow for a 2x barlow. This one is 4 months old and in like new condition, except for the usual set-screw marks. It is a no-name model, but of nice quality (anodized aluminum and chrome, multicoated 2-element). I paid $45 for this, and would like to get $35 + shipping, or I would make a trade for a nice 2x barlow. Comes with both end caps and box. Thanks!
