I have had great luck with Joyce - and know others here have as well.

General clean up and glass re-silvered $85 each + $12 shipping (that's what it cost me 2-3 years ago)
Was about a 2 week turnaround
If you want to take your chances taking out the glass from the rubber/plastic housing and putting it back yourself you can also try:
Silver Service, Inc.
16120 Vandustrial Lane
South Holland, Illinois 60473
708-331-5501
I think they were $15 each, + $10 S & H when I researched before using Joyce.
