engagement/shower thank you's

I was thinking of getting cute yet inexpensive thank you cards for engagement and shower gifts, preferably with our names printed on the front or a monogram of some sort... or just a G for his (and my future) last name.

Anyone know of a good website or place to get these at a good price??

I actaully went to Paper Presentation this weekend and I saw blank cards with a monogram (one letter) on the front in silver. They had all the letters of the alphabet...not sure about the price but I love that place!!
