It is cheap, because it has been in production for a very long time. With very little revision since the original, which to me only seems to serve as a testament to how good it is. It is a classic, by now. And will probably be refered to as legendary some day. Like I said if you are going for Super authentic acoustic drums, SR-16 is probably not your best bet. But it does electronica in spades, with excellent programibilty (you can tweak the pitch of each drum, it's pan settings, volume etc.), then save custom drum kits. And I really like the trigger pads. The sequencer is a little quirky in the way you program, but once you have created a couple of basic patterns, you'll be creating complex stuff in no time. Basically you can save patterns (It comes preloaded with a bunch covering many genres), then you can arrange the patterns into songs (You don't have to use patterns, you can sequence an entire song if you like, but it uses more memory). And then you can use the footswitches to control start/stop, pattern selection, fills etc. (Each Pattern is made up of 2 independent patterns, and 2 independant fills). I've had mine for about 7 years now, and I still turn too it quite often (Especially if I'm looking for a really fat kick drum). The 4 outputs is nice too. I set mine up to have a kick on one, snare on another, and all the rest of the kit as a stereo pair, so I can process the kick and snare seperately through my mixer.
