Hi Christine,
As Brian points out I have an Uzi too. I have had it for just over a year and to me it is the most suited out of all the digital cameras for bird photography - unless you can afford a Canon D60 + lens. It was still quite a chunk out of my budget, but I can honestly say it is well worth the money.
It carries almost the same specification as the Canon Pro90IS which does have a slightly higher megapixel rating - I would have had one of them instead, but they were at bit dearer at the time I was looking.
Both cameras have been discontinued, but a few new ones can still be found on the Net over here, secondhand or refurbished from Olympus. I'd still recommend them as nothing has directly replaced them in terms of features.
The Olympus C730 is very similar in specification and there have been some very good reviews of it. It does have more megapixels and a 10x lens, though from what I've read, the 10x is more geared to the wideangle rather than telephoto range and so equates more to something like 8x on the Uzi. The other thing being that the 730 has no image stabiliser, which at long zoom lengths and especially in dull conditions really means that a tripod is necessary.
Another point is that each of these cameras can be used in conjunction with tele-extension lenses which can be coupled together to give around 1200-1500 mm 35mm equivalent, though some degradation of image occurs, but I find it is often 'better to have than not have' a shot.
dpreview is a very good place to look as you can read actual owners reviews as well as the official ones. Stevesdigicams is another good review site.
Keep an eye on the Gallery here, hopefully it won't be too long before it's up and running again. All of my photos are with the Uzi, many of them with the tele-extension lenses too. Other members also use this camera for comparison.
If you have any particular queries about the camera, feel free to post them or send me a PM.
It's a good point about Digiscoping. If you already have a scope it's a very good option, though a little expensive if starting from scratch. The Digiscoping forum on here is very good for advice and tips.
