If you are buying in the United States, I suggest the purchase of some 2012 series (34/35xx, 2xx5) or 2013 (2xx7, 3xx7) model. Buying refurbished you will have a good advantage in price. I just bought a 3597 in the US for $ 220. You get a 3590 for $ 180, a very attractive price. Forget models like the 1xxx and older, unless that you wishes to spend the minimum possible.
