I prefer the tape and use it like a hinge. The print can expand/contract at a different rate than the matte or backing, so glue can cause it to buckle. Plus tape is a lot easier to get past if you ever want to remove the print. If you are on a budget, you can use the same frame and rotate the print every couple of months.
I am actually in the process if ordering prints/getting frames for a whole bunch of photos that I intend on decorating my house with, and the info in this thread and the other one mark linked to was great. So thanks a lot Mark (and Roroco, cause the advice wouldn't have come if you hadn't asked the question).
