I would highly recommend
Acrylite OP3. It's in most of my frames, blocks 98% of UV light, and is reasonably priced. For my 30x40 frames, with acid free backing, and Acrylite OP3 plexi (most call it acrylic), they are about $100, and that's with wood frames that are specially ordered, cut/assembled, and the backing and acrylic cut to size. I get them from
Florida Frames, Inc. From the few framers whom I've gotten stuff from, they are the best, in terms of workmanship, quality of materials, and price, and it would be even less expensive if the frames weren't specially ordered. I'm not sure about how much it would be to ship them, but you may want to call them to see if they can at least steer you in the right direction.
I use a
Logan F500 point driver with
Logan F55 flexible points to secure the backing, which is nice because I can adjust the pressure to the backing. I always put the points in the frame when the poster is not in the frame, then bend them to remove the backing, and put the poster in, put the backing in, and bend the points to hold the backing in place and at the right pressure. I usually bend the top points slightly tight, then the sides and lower edge just enough for a good fit (it's easy to see if there is too much pressure on the backing or not enough). Only takes a couple minutes. Use
Novus #1 for cleaner/anti static (I just use it once on both sides of the acrylic before putting a poster in the frame), and then when posters are in frames, just wipe the outer acrylic with a microfiber towel and they are clean, (and when changing posters wipe the inside). With the anti static/protective properties of it, it's like a coat of wax for acrylic.
That about covers the topic of framing my humble collection, just figured I'd explain that in case anyone is interested.
