i too belive that this is base on your personal ease of mind on how much you willing to spend and how you will be using your camera. there is NO Comparison between a Canon DSLR, XTI, etc., and the Canon Powershot S1/2/3.
the Canon powershot S3 IS is the best rated Point & Shot camera with the options and features that makes it very closed to its BIG Brother, but with less of the cost.
if you want a little more bang to your S3, all you have to do is add about $150-$250 more in accessories (flash, lens, etc.,) and it can perform close to its BIG Brother.
example::
Canon Powershot S3 IS (Ben's Bargains, Dell special promo) = $303-$365
Telephoto Lens (Sony, Raynox, Olympic, etc... eBay) = $25-$80
Wide Angle Lens (Sony, Raynox, Olympic, etc... eBay) = $25-$80
External Flash, Flash Bracket (Canon, Sunpak, etc.,) = $25-$50
=============== TOTAL = $500-$550 ===============
EOS Digital Rebel XTi SLR Camera with 18-55 mm Lens = $771.95
Canon 580EX Speedlite E-TTL II Shoe Mount Flash with Quantum Turbo Battery, Charger & Connecting Cable = $809
Canon Telephoto EF 135mm f/2.0L USM Lens = $899
Canon Super Wide Angle EF 14mm f/2.8L USM Lens = $1,749
so then you need a Telephoto, etc., then you need a Wide angle etc., so your total will be $800 + $900-3,000 for additional lens, etc.,..
if you have the money, go for it..
===============
but the Canon Powershot S3 IS standard can do so much already and with the extra add-ons.. it can do even more for under $550.
but i know that within the next 7-8 yrs later, i will jump into the dSLR scene.
(after i sell my house, car.. just kidding)You're not comparing apples to apples.
A dSLR excels in response time, AF speed, ability to pair fast lenses (for low DOF and better low-light performances), wider-angle lenses, ability to change lenses, potentially better IQ and the naturally lower DOF. You can't just say 'buy all this and it'll become close to it's big brother'. You can't compensate critical advantages of a dSLR by piling on plenty of S3 accessories. None of the accessories you just mentioned addressed any of the primary benefits I listed above, except the wide-angle converter.
Secondly, you made a pretty bad illustration of your point with that dSLR purchase list. A 580EX with a power-bundle pack for $800? No thanks. I also don't get why you chucked in the 135mm f/2L and the 14mm f/2.8L. Seems like you just decided to throw in a few random expensive lenses just to bump up the price, even though those lenses don't help to illustrate a comparison to the S3 at all. The S3's 12x optical zoom equates to roughly 420mm FF-equivalent FL. Why not chuck in a 100-400L? It's expensive too, but atleast it holds much more relevance to the point than throwing in something random like the 135L & 14L primes.
I know you don't have much experience with dSLRs and I'm not trying to be unfairly critical, but my point is your limited knowledge on them will have a tendency to translate to inaccurate & erratic advice for these types of forumite issues - unfortunately this really showed in your last post.
