Plane Sailing said:I don't know if you've access to Monte Cooks Arcana Unearthed/Evolved, but I've heard people say nice things about the 'unfettered' class.
HOWEVER,
Personally, I think that the best light armoured, stylish fighter *should* be a fighter - I'd like to see more feats that enabled a clever, charismatic fighter to hold his own against a strong tough fighter. At the moment the core has plenty of feats for strong fighters and some good ones for intelligent fighters (expertise/improved trip/disarm) but doesn't really have anything for charismatic fighters.
Introduce some good feats for charismatic fighters and I think you'd be good to go.
The other classic option for a duellist character is the rogue of course - the lightly armoured, agile fighter, tumbling all over the shop, uncannily dodging and bluffing his opponent and getting in nasty well-placed shots with his rapier. Boost the Con to improve his hit points (and staying power), use some SRD feats like Cloak Dance to give him some style and mechanical bonuses (a miss chance in that case), use his charisma skills of bluff and perform for style - you know what I mean.
Although 'everyone knows' that rogue != thief, it is surprising how often I've seen them played in just that fashion!
Cheers
If you want to play a charismatic fighter, the Dashing Swordsman PRC is your best option.
