I think the kit you're looking at there will satisfy you for a while. but eventually, you're going to want to replace EVERYTHING - the body and all the glass. You have to start somewhere though and that's not a bad way to start out, IMO
With the D50, though, you can use lenses that don't have autofocus motors built into them. This includes a number of cheap but awesome lenses both new and old.
im not looking to start making money off of my pictures, but i would like to get into it for myself. i want to learn how to take better pictures. i realize a DSLR will not make my pictures better and that i will need to learn HOW to use it, unlike most P&S cameras.
