I see a few used ones for sale now, and I'm wanting to know how to tell the revised versions from the older ones. Serial number? or some other markings? Thanks, Fred (friend of Ricky)
I had the same issue. If you look on top of the unit, it should have a revision letter. Such as Rev-A or Rev-C. I know the Rev-A one's have had problems (I owned one and got rid of it). But I'm sure others will have more details. Ask the seller(s) to give you the Rev letter off the top of the unit. From my understanding, steer away from Rev-A models. I'm sure a lot of used ones are up for sale.
