There are lances, if I recall - they're in the "Spear" class. Not sure which book they're from. Check PHB, PHB2, AV, and AV2.
If you go fighter, I think there are some nice feats you can take which help build up your charge:
I'm thinking:
Mark of Handling
Powerful Charge (+2 damage on charge)
Hewing Charge (+Con damage on charge)
Surprising Charge (+1W damage on charge vs Combat Advantage)
Barreling Charge
Overrun Critical (Crit on charge pushes 1 and knocks prone)
You might also consider the following powers:
Fighter Encounter 3
Bull Charge - Charge for 2W, Temp HP, push 1, and chance to knock prone
Fighter Daily 5
Brutal Advance - First attack for 1W, push 3, then you can charge for 1W and knock prone.
Cometfall Charge - Charge for 3W+Str+Con
Fighter Encounter 7
Hydra Charge - Charge for close burst 1, 1W
Fighter Daily 9
Murderous Assault - First attack for 2W, then you can charge another target
Some other interesting powers which may be worth multiclassing for or taking a half-elf dilettante for:
Barbarian At-Will 1
Howling Strike - Charge for 1W + 1d6 + Str
Paladin Daily 1
Glorious Charge - Charge for 2W, then heal each ally within 2 squares of you
Ranger Encounter 3
Avenging Charge - Charge for 2W as an Immediate Interrupt when somebody attacks your ally.
