I've used Oracal's wall material a few times (3628 I believe), it does the job, but you do need to leave a white border (around 1/4") around the print or it'll start to curl. I've laminated it with 210 laminate before and have a few samples still sticking to my wall good.
Most people highly recommend Phototex above all others though and it can be printed to the edge and not curl. I have not gotten a chance to use it yet.
