Reifel Migratory Bird Refuge near Vancouver, BC, February 2000. This was taken on 400 speed print film, and scanned from the negative.
Canon Elan 2, 75-300 IS lens and Tamron-F 2x teleconverter
This gives effectively 6x magnification with a built-in image stabilizer that does a good job at reducing camera shake. I use this for hand-held shots, though the IS technology is less effective with the doubler on it.
This flicker was waiting for access to the suet feeder in our backyard in August of 2000. This shot was also taken on 400 speed print film, and scanned from the negative.
When conditions are not perfect, this is a very difficult setup to use. The picture can be disrupted by the slightest camera shake, or by the subject moving at the wrong moment. However, I've also gotten some incredible shots that make the piles of bad prints worth it...
This wattlebird was photographed behind our motel at the Grampians in Victoria, Australia in September of 1999. This shot was also taken on 400 speed print film, and scanned from the negative.
Canon D60, 75-300 IS lens and Tamron-F 2x teleconverter
In October of 2002, I finally switched to a completely digital configuration. The main drawback I have noticed so far is that more distant subjects have less precision in the image than on print or slide film. It also eats batteries for lunch, requiring a recharge after only a day or so in the field.
However, there are great advantages to being able to preview and delete shots on the spot, and not having to deal with processing, storage, cleaning, scanning, etc. of negatives and slides.

Canon Powershot A85 digiscoping with Swarovski 80-series scope
In January of 2005, I got a digiscoping setup using an instamatic Canon camera. This has worked out better than I hoped: you can scope anywhere from a few feet to hundreds of yards away, and the camera auto-focuses through the lens (which helps my weak vision a bit). The photo quality is fairly good even in overcast conditions, though it's necessary to crop the dark halo. A close target makes that difficult.
