is it possible to get a good sounding used large format analog console that will reliably stay in good working condition for at least 5 years - without spending loads in maintenance - suitable mainly for mixing for less than 150k (i know that is the least realistic part about it)?

when i search the net i occasionally find used 6k's, 4k's and sometimes even v3's or vr's that seem to be somewhat financially *in reach*. what can one expect from these desks? how much do you have to spend each year to keep them working? how about the sound of these 15 year old consoles?

i'd be looking for an inline console with a minimum of 48 channels, no more than 64, dynamics, automation. i'd be willing to spend a little more if i could get a board with moving fader automation.
did i mention it should be cheap?
