As Dedaien said... you might want to save up for a decent weapon instead of using the 400 plat you have now.
Top choices would be:
Copper Hammer of Striking (15k or so), a 13/20 1HB with a 175 point proc (with 0 sec stun, for aggro), plus good stats, procs at 1st, but rec level is either 53 or 56
Sword of the Bloodsworn (12k or so), a 13/19 1HS with a 75 point proc (with 0 sec stun, for aggro), plus good stats, procs at 1st (but rec level is 56)
Blackened Acrylia Blade (6k or so), 14/22 1HS with no proc, but decent stats
Frostbringer (4k or so), 12/22 1HS with 60 dam proc and AC debuff, procs at 41st, I believe
If you can't wait, get a Centi Shortsword (250pp), Stone Bladed Axe (250pp), or a Venomous Axe of the Velium Brood (procs at 35th, stats are only moderate) if you can find one around 250-350 plat. I've seen them up to around 600pp, but usually cheaper if you are patient.
