Hi Joe, You should take look at the seller feedback, usualy this will tell the honesty but some will not because here at audigon they can play around with feedback system they can actualy leave good or bad feedback to one another without any transaction so B-careful! You should know the seller real email or even phone num. I'm buying and selling audio gears here at audiogon over 30 transactions only met one bad apple, who did not completed tranacstion( as-h?). What I'm saying is there are alot of good "Audiogonian" doing business with honesty and love of hi-end audio>>>>(hopefully you'll get the easy and fast transaction.) OK, COD is Collect On Delivery You will have to get cash or MO.( up on the seller request) ready when UPS/USPS?FED-EX arrive (MO 'll get to him or her quicker than cash) this way will make sure that you'll see the unit(box) first before you pay. Paypal.com is a service that once you register with them you can pay by cradit card thought them to the seller that already a paypal's member. This'll protect you some....I don't know how to tell you all about it please learn more at paypal.com...For me both are OK. but for other they don't like paypal (They'll post comment soon,mmm I guess) HAPPY NEW GEAR<, GOOD LUCK TO YOU ALL! Regards, Rute.
