Recommended beginning soldering kits

I'm looking for a kit that will give me some practice holding wires in place and soldering connections, hopefully also while giving me a completed object or set of objects that's fun at the end. I'm not completely new to soldering; I've done a couple simple kits and some repair of model trains with loose wires, but I definitely could be a lot better at it and I'd like some guided practice. Emphasis on the "guided," I'm not looking for additional things to repair, I really want a straightforward kit, a range of difficulties in connections would also be great. Any recommendations?
