When I got my 1998 Odyssey, I was directed by the dealer parts counter
to Helm, where I bought a paperback service manual that was pretty
good. I just bought a 2007 EX and went to Helm's website and saw that they have several manuals for
the car, as well as an online service.

Does anyone know which manuals I need? Maybe the Service and the
Electrical Troubleshooting Guide, but not the rest? Has anyone tried
the online service? For my Subaru, a different website had something
similar, that would let you download up to 20 PDFs/hr. for 3 days for
$35. If you downloaded all day for 3 days, there was just enough time
to get all the manuals.
