Like has been said before, don't get one for the sake of getting one. But, if you know you get on well with classic, Anser-type putters, you can't go wrong.
In my opinion they're not the softest feel-wise (say, to an Odyssey Black Series), but they give you the most 'responsive' feel.
I've had mine for about 10 years now and I haven't had anything else in the bag for that time.
You can get them on EBay, but make sure it's in good condition. Yes, these things rust,...
