I've got all of Angel, Firefly and Buffy on DVD - they're all back in Middlesbrough like, but can get some sent down easily.
Been a while since I've seen "Smile Time", but I can't remember it being that great. Angel wise i'd suggest "Hero" or "A Hole in the World".
For Buffy i'd go with "The Gift" as a suggestion.
Definitely want to see Dr Horrible again though
