You shop in the wrong place.
www.Supermediastore.com has taiyo/yuden printable CD-Rs for $36 for 100. A full complement of ink is $17 and does around 400 to 500 CDs depending on the artwork (you might run out of some colors faster than other depending on the picture you are printing) So, my actual cost for 500 CDs is $197. That is less than $0.49/each.

And Al is right, it comes down to the type of job. As I said, ink jet printing is not bad for personal use, for proof copies, one-offs and such. Maybe even for demos, though I'd personally be more than willing to pay $1.78 for a demo that looked like a commercial CD.
And if one is just doing one-offs of their own work, unless they pump out a CD's worth of new material every few weeks, they'd better find plenty of use for the printer outside of just making CDs to make the initial investemnt worthwhile (a single one-off will still cost $130 for printer and a spindle of discs

)
For something like what Rami describes, an indie release for public sale and distribution, I would recommend getting them done by the service, though. Granted this only IMHO and FWIW subjective opinion, but the way I see it, there's no excuse in that case not to put the best presentation forward.
Even if one sold their disc for only $9.95, that still leaves $8.13 gross per disc. One can add the full color heavy bond 2-panel sleeve and tray card for $.90/disc and still be making $7.13 gross profit per disc. At that rate, one only has to sell one quarter of their inventory (25 discs) before breaking even, everything beyond that is pure profit.
Buying a new printer and discs one's self, the break even point would be at 14 discs, but that's not including the extra cost of making the 2-sided sleeves and tray cards on 2-sided heavy bond gloss stock.
Sure the pro printing remains more expensive, but it's far from prohibitive, has a vey low break even point (assuming one's music is good enough to sell 25 measley copies to the entire world

), and looks like - because it is - the real deal. Can't beat it IMHO.
