I bought ten 16x20 frames with plexi from Frame Destination a few years ago for a show. I've been switching stuff in and out of those frames ever since. Our photo club and local art club frequently have little shows in places around the area and I need two or three pieces. I haven't had to buy more frames for awhile. Yes, it's an investment, but worth doing right. I LOVE the way FDI packages and ships their frames, too, btw. Those boxes are still in use for storage of my framed work. I do save by cutting my own mats.
