I was looking for one of these for some time.  Found them on ebay going for
$150.  Advance Auto Parts/Parts America online had it listed for $105, but
was out of stock last month and again when I tried this month.  I found it
listed on PepBoys.com for $101.  Their website was not too slick, but I did
get the unit in a few days for that price.  Free Shipping and no tax for
me, ymmv...  When I was recently travelling, I tried several Pep Boys
stores to see if I could get one, but they said they don't carry them in
the stores anymore...
