I also have no problem with grading reprints as long as they are labeled correctly.
GAI is a whole different story. For a good laugh check out the web site.
http://www.globalauth.com/ My 2 favorite services are "certified sleeve" they put your card into a cheap card saver 2 and put a label on it.
The "Duel Certification" though is a very needed product. This service lets you get your PSA/SCG/Beckett cards certified by GAI. They even put their sticker on your PSA/SCG/Beckett slab so everyone knows it was approved by the best in the business.
