What sort of help do you need? I use a JSL focuser (get 'em from
TAC's own Crazy Ed). JMI also has some nice focusers, and don't
forget Moonlight <http://www.focuser.com> or the Feathertouch, which
many people believe to be the nicest focuser currently going.
Be prepared to pay for a nice focuser, though.
Telescope Optics aka, Ruuten and VanVenrooij, won't help you to
much, as its just theory, no practice. I'll just say that a 2"
focuser is a good idea even if you only use 1-1/4" EP's, because
its easier to baffle effectively, and all the really good focusers
are available only in 2".
