I agree that the guys at Sadowsky will be very helpfull. My feelings are that it makes good sense to by a Sadowsky over cheaper alternatives because not alone are you getting a superior instrument, but also because of the great after sales support from the sadowsky team.
I think you should look at trying to set up your own instrument. I was quite hesitant initially with regards to doing my own set up and this article was recomended to me by Roger and is very informative. www.sadowsky.com/media/support/library/.../bp0996_bass_setup.pdf
. A chat with one of the guys at Sadowsky will get you started.
Also Elixir nanoweb strings might be worthy of consideration. I find that they match my Sadowsky bass (Ash body/maple neck) very well. Be sure to wipe them down after each gig. They last a really long time and you avoid the hassle of changing strings every few weeks.
best of luck.
