If you already have a smaller four bladed easel, and use the 16x20 for that size alone, then buying a used two blade easel is not too big a deal. I have recently purchased two of them on ebay for less than $60 each, one of which is in very good condition (the other one is quite servicable as well, but boy is it ever "ugly!"). I would rather have been able to buy a four blade easel, but the prices are waaaay outaline in my opinion. The two blade is going to do just fine.
