I think I've finally come to the realization that I need a 4 blade easel. I'd rather not spend a fortune right now, and most of what I see on Ebay are Saunders, and some LPL easels. There appears to be various types of Saunders easels. Does anyone have anything good (or bad) specifically to say about Saunders in general? How about the various models? What are the differences between "Universal", "V-Track", "Slim Track"? Thanks all.
