Buying used can be a good option; you said several years but not how many. 5? 10? 40? 50? I've bought most of my equipment used but I've drawn the line at things made in the 70's and 80's - some parts are not available for certain models, so you might be left scrounging for second hand parts or trying to cobble together your own. A selling point often touted for older MacIntosh units is that they can be serviced no matter how old they are, but even with those certain parts are not available.
