This is the closest I could come Ka-chunk the near sighted dwarf. I would take off the axe head and just make it a staff for a monk. He is available over at fantization miniatures.
There's a dwarf brawler at Discount Hobby; he's wearing a cloak and hood and carrying a mug, and swinging a mailed fist. Could be a nice figure for a Drunken Master type.
The WOTC Dwarf Caver from Deathknell could easily be a Monk double wielding kama (he has two picks). Or the weapons could be easily customized or removed. He is wearing a helmet, but is otherwise a non-armored Dwarf.
Iron Kingdoms (The Monsternomicon & Warmachine guys) have a Dwarf Rogue that looks sort of like a monk. (he's a 2nd story man, but is less heavily armored than many).
I've got some old Ral-Partha Merchants that could double as Monks (Rich clothing, but no hint of weapons).
I've got some Reaper Dwarves, merhcants again, that lack the weapons & heavy armor most dwarf minis have. I have a Dwarven Brew-Miester set that includes a min that could easily be a druken master PRC. Reaper has also really begun to expand their line lately. I just picked up a Orc Monk, and a Gnome Barbarian is available. A dwarven monk is propably in the monks.
Maybe check out Magnificaent Egos. (they should have a website). I'm pretty sure they have an ogre grappler, so they might have an swarf monk.
