I would add a vote for the Chipmunk - I've never had the good fortune to fly a Spitfire but if the Chipmunk is the 'poor man's Spitfire' then the Spit must be pretty special.
I'd also like to suggest the Slingsby T.67 - lacking in roll rate (and power in some versions) but that is another aeroplane that seems to respond almost telepathically. I would suggest the Extra 300 but unlike the aforementioned two that is significantly more likely to bite if you get something a bit wrong...
