If you're not a tone whore who's willing to pay exponentially more $$ for the ability to eek sweeter tone out of a carved instrument, laminate is the way to go (like Flank's and mine). They don't usually require that much maintinence but there is some routine work that should be done from time to time (like replacing the sound post) that can avoid much greater problems later. Although, I went for 11 or 12 years without replacing my sound post. I could really tell the difference in tone when I did, though.
I don't really trust myself with anything beyond changing the strings and cleaning the instrument because the slightest movement of the bridge (or numerous other things) can have a huge impact on tone and playability. But then, there are those who play jazz and rockabilly (among other things) who never have any work done at all and are perfectly happy with their instrument.
