Does the SDS provide any facilities for data logging? The site doesn't seem to list anything specific. If not shouldn't you add in the cost of either dyno time or a WO2 setup with some means of datalogging when considering the total price?
Its obvious from the support it has on this board that the SDS is a solid system for the CA, but it still seems a lot more expensive than a piggyback that includes data logging, and not all that much cheaper than, say, a Haltech with built-in data logging and a pleasant graphical display.

Even with a haltech, motec, AEM, Links EMS, microtec, or whatever, you still will need to spend money on dyno time. Those pretty graphical displays you speak of does nothing for novice tuners, but confuse the hell out of most of them. Remember these 3 letters S.D.S or Simple Digital Systems. It is just what it says it is "Simple". If you're a horrible tuner, a pleasant graphical display won't prevent your power plant from melting down if you screwed up.
However, those that are really keen on using piggy back systems for their motors, that's your option. Anyone trying to use burnt chips, more power to you and wish you the best of luck. I like the powerFC's initial function, but have yet to see anyone with one on their CA18DET set-ups. We have one user that uses a haltech on his Nissan Pulsar with CA18DET, one user (which is me) that actually tunes in real time with an SDS system, some with chips, SAFCs, and most are stock. Until someone explores other systems with this motor and with some success, we can only go with what seems to be the most cost effective for the gains. I've gotten the opportunity to tune both SDS and microtec on the CA18DET and I personally think the SDS is much more easier to tune despite the fact that it doesn't offer data logging or pretty colored graphical screens. And tuning on the SR20DET was even easier than the CA IMHO. It's all about preference and what's proven.
