In my expierence the way Keh grades.
Excellent would be called new by many shops or at the very least mint.
Bargain can range from a scratch on the camera base to a good user item. Bargain grade always works but if you're worried about looks the higher grades are nicer. OTOH I really have bought bargrain grade that needed a loupe to find the scratches.
IMHO Best part about KEH is they are REALLY honest. I bought a shade that didn't include the mounting bits. Pretty useless. Some shops would have shrugged. KEH gave me a quick refund with no questions asked. They've shipped the wrong hole size lensboard and just told me to keep it and then shipped the right one at their cost.
How much is shipping to Europe?
