I would say stay away. I went here
to their authentic blank jersey page, and the telltale sign, at least for me, is that they advertise sizes as "M/48" for example. Well...authentic jerseys are never advertised with letters and numbers at the same time - only websites and ebay sellers that are selling fakes do that.
Also, there is no size 48; it's size 46.
If you want a fake jersey, just use borntrade...at least they are cheap and you know you are getting a fake. That site might be legit, but they would make me nervous.
This site, on the other hand, is completely legit (they do customizing for the Ducks I think) and they are having a big sale to get rid of all of their Edge 1.0 stock. If you don't mind a blank jersey, you can't beat $130 really for an authentic. They customize too, but if you are a stickler for getting the exact fonts the Pens use, you might want to get it done somewhere local.
Anyone that has been wanting to get a cheaper authentic Edge model, I would suggest hoping on this sale. The Edge 1.0 model has been discontinued and replaced by Reebok with, from everything I've read, a completely inferior model made in Indonesia that uses very poor materials. If you want an Edge 1.0, I'd get it now.http://www.hockeymonkey.com/reebok-hock ... c-pit.html
Edit: I think they also have the Premier/Replica models on sale, too.
