What are the better quality invitation companies?

I've heard of a few ladies having problems with Not from a Box. I'm pretty sure it's a small company, and sometimes they bite off more than they can chew. Have you searched the NYC board on weddingchannel.com? A lot of the ladies over there have used higher end invitations.

I really haven't started seriously looking for invitations yet, but I really like some of Gaddis' designs, and I am currently in love with some of the letterpress designs from Marsville Letterpress, which is a Canadian company, and the exchange rate makes her invitations really affordable. (compared to most other letterpress companies) I'm still trying to convince FH, he doesn't like the look of letterpress.

Also, I saw your post about Lizard designs. I received a sample from them, and the invitation was really nice, but I'm not thrilled with the print. It seems like it was done with a home printer, and that's not exactly the look I'm going for. I did love the sample though, and they're still in the running.
