Digital video camera

My wife wants one for a combined Xmas/Bday present. I know it won’t arrive by Xmas if I order now, but that’s not really an issue. I just need to know what to look for and what to avoid. I’d prefer spending around $300, but I can go a bit higher if necessary. It doesn’t need to be fancy; just something for her to video cat shannigans and such. Any recommendations?
