Can you recommend some classical CD's for me?

I don't have any classical CD's in my collection.
There is so much product out there, I don't know where to start.
I would like preferrably SACD but not totally necessary if the redbook CD is well recorded.
I don't want any vocals.
I am not a big fan of large classical orchestras.
I like classical guitar, I enjoy the cello.
I guess more stringed instrument related, instrumental classical music.
Thanks Glen
