Wanting digital camera, shoot weddings,canon d5, 20d & nikon d200,apple vs. pc,printers,scanner,etc.any sugg?

I'm assuming you want to shoot weddings with a digital SLR. Quite frankly, any one of the cameras you listed are fantastic at it, it comes down to which brand you are most familiar with. I'm a Nikon shooter since the days of the F3, so I have a D70, as I'm most familiar with that line. Look at dpreview.com for more, and DEFINITELY take a day or so to rent each before hand and get a feel for each before you decide. All the wiz-bang bells and whistles in the world mean squat if you miss a shot because you were fumbling with a camera. I shoot Nikon, my buddy shoots Canon. Each of us takes great shots. It's not the tools you use, it's the pictures you take.

As far as Mac v. PC, both run Photoshop equally well, but I'm a Mac guy from the days of the 128k Mac, so I'm biased that way :-). However, since ColorSync technology is rooted into the Mac, I've found that platform allows for the best picture-edit-print solution. Either OS will work with your photolab. I like to organize with iPhoto before I send them off to be printed. but Picasa from Google works well on the PC, too.

Scanners? Well, my Epson works good, I have the 35mm slide adapter to add in my previous work. I used an Agfa for years, though, and had great results with it as well. But really, I've not used a scanner on a job for 4 years now.

You haven't mentioned lighting. Look at getting an adapter to take your strobe off your camera, or maybe use a small soft-box on it. Maybe a Lumedyne or other battery-powered strobe with an umbrella. You want to avoid the typical flash-on-camera look that anyone's Aunt Mabel can get with her $10 disposable. You're a pro. Your pictures should look like it.

So really, it comes down to what tools you feel most comfortable with. What's important, though, is to give yourself an edge over the competition, and I've found that using digitally-printed books like the ones available thru iPhoto or at mypublisher.com are a great item to include in your package. They're cheap, and they really make it special to the client.

And as for photolabs, find one you can develop a relationship with, and get to know how they print their files. Ask for their color profiles on a disk, and then go thru the primers on color management at prodigitalimage.com.This will help get your scanner in sync with the lab, too.

And after ALL of that, you still need a way to display your brand and images online. I recommend WebFolio (http://folio1.velo3.net ) as inexpensive online marketing solution for photographers. Easy-to-use and powerful as all get out, I like it because it gives you the look/feel of a Flash-driven site, but with the search engine visibility of HTML.

The quality and resolution of even the more expensive digital cameras is still not as good as the standard wedding photographers 2 1/4"/120mm cameras. For the prices people pay for wedding pictures you should stick to film. But then people's standards and expectations become lower every day and digital weddings may even be acceptable to some of them.
