I didn't have much money to spend but I also wanted some thing of how you say better quality/grade.
Did a lot of research on some real good stuff out of my price range if I bought retail. Living near a larger city where there are a good quanity of pawn shops and didn't mind possiably buying a stolen product is where I decided to shop.
How ever my banker objected to that idea for a couple reasons.
(1. as stated the product may have been stolen from some one. Don't want to get caught in a play ground with a hot machine by the former owner, carry the bill of sale with you.
(2. product may not work properly, Make sure it is returnable if not satisfied.
(3 owners manuals may not come with the machine. Those can be had on line in PDF form so isn't a problem except with the banker.
So if your your own banker and do not have a truck load of moneies check out some pawn shops.
Never the less waiting a few years longer and storeing change in a buried PCV (GPS marked of course) pipe I was able to buy a fairly decent machine.
