It always depends on the budget -- we went with cuff links.
I went to a shop(Thistle and Clover) in old town St Charles and they had family crests.
I had something made with my crest and his and a prayer under it.
Framed it cost about 50.00, it was printed on old looking paper
We have it having in the livingroom by the door, so we see it everyday.
Heh -- I see now it was a "grooms gift" not "groomsmen gifts". My husband and I chose not to exchange gifts on our wedding day.
Silver plated and engraved items, such as money clips or cuff links are nice. Check out www.chicweddingfavors.com for good prices on groom's gifts.
