Refernce Wanted... Music for Ceremony - Art Strings

Hi...

I'm planning a wedding for April, 06. I wanted to use a string quartet for the ceremony and came upon Art Strings ( http://www.art-strings.com) online. They seem good and all, but I would feel so much better if someone... anyone knew of these people first hand!

Can anyone supply any information or a reference??!!

Greatly Appreciate it!

Thanks!
