As with the others, get the young lady into a store to handle as many goods as possible (Jessops? for the latest models) Of those that feel right, see if they have the older bodies in and make a note of the ones that do feel right.
If you have a local used camera store, they will be the next place. Pop in and mention which bodies felt good, see what they have to hold of the older models.
As its likely to be a crop, see whether they have a deal with kit lens and/or a 30/35mm prime lens.
Remember you need a memory card or two - batteries should be ok initially and a built in flash on the body would be sufficient for now.
Probably entry model although I prefer a little better if you can afford it.
As I'm nikon, I'd say a d70 d80 or d90 used, d200 if you have a good bargain.
nikon 35mm f1.8 (new in jessops is 170 - so used around 100?) or 50mm f1.8 new around 100ukp so used around 75?
Canon, perhaps a 20d or 30d? not sure of prices. The 450d or 500d for a newer camera?
