Family Tree DNA only place for Y and mtDNA testing, has projects
23andme gives health results, haplogroups
Ancestry.com is least likely to have matches for recent immigrants

Jewish Y Haplogroups: J1c3, J2a cohanim

Kitty's Guidelines for Jewish DNA Matches

At least one segment > 20 cM
Another segment > 10 cM
Several more good sized segments
