Hi Laurie,
I am just a bit more advanced than you are, but I will try to answer your
questions.
1. The Y test is very helpful when trying to establish a relationship where
the surnames are the same (except possibly for spelling). In that case, you
need to recruit as many BUDGA/OR men as possible to determine a link, but at
a minimum your brother and a man >from the other family. The Y test only
works for male descendants on the paternal line (or surname) line. You
should explore FamilyTreeDNA's surname projects and see if there is one for
BUDGAR. Do the same for 23 and me.
2. The mtDNA test is almost useless for genealogy unless you do the full
test - and it only picks up the maternal line (eg mother's mother's mother
etc). This is because the mtDNA mutates much slower than the Y DNA. I have
found one double match with someone in the family finder - but we don't know
who the common ancestor is, and I have many matches with people whose
mothers were in the US in the 1700's, while on my mother's side, I am a
first generation American.
3. The family finder test is not restricted to one line (that is a plus)
but that means you get tons of matches and you don't necessarily have a clue
how you are related. But it has given me a clue that my grandmother's
statement about having "yichus" is true. I just haven't worked it out yet.
Jewish genealogy is not easy and this isn't either.
4. The reasons that I prefer FamilyTreeDNA to 23 and me are: that it does
not have health information, which makes it easier to convince a cousin to
test since you wouldn't be getting his/her personal information (and frankly
I do not want the health information) and also that it has a much larger
database, especially for Jews.
5. That said, there are websites www.Ysearch.org and www.gedmatch.com
where you can upload the results of "your" tests regardless of testing
company and get comparisons to their databases.

I've been researching my genealogy for years, but have not yet used a DNA
test, and have lots of very basic questions about them...
