Hi,
Yes, I have an E-500. I've had it about 6 months. I got it mail order from Costco with 2 lenses and got a good price. I forgot how much.
I am very happy with the camera. I have yet to put it through it paces. My wife and I leave in 3 weeks for vacation and it'll get a good workout then.
There are a lot of settings. I'm sure the other digital SLR's are the same. I'm still getting used to them. I like the digital display and that it'll write to a Xd or a CF memory card. I don't like that I have to use an external charger but the battery lasts a long time between charges.
If you have any specific questions please let me know.
