Monk-Kensai (Complete Warrior)
PROS: magic weapon unarmed strikes; BIG boost to strength a couple times a day; Concentration checks in place of Reflex saves (very useful for high-CON monks with evasion ... !); fighter BAB; can multiclass back and forth with monk.
CONS: every level of Kensai takes away monk abilities. You may want/need to skip the las level or two of Kensai.
Monk-Initiate of Pistis Sophia (Book of Exalted Deeds)
PROS: most core monk abilities continue to increase (speed, damage, flurry, ki strike, AC bonus); uncanny dodge; improved evasion; extra vows; smite evil; detect evil; a REAL "good-guy".
... this one could work especially well with a Vow of Poverty build, btw...
CONS: a really good-aligned character (to a fault); loss of non-core-concept monk abilities at higher levels
