if you want to get a ddr mobo. go for the asus a7m266, you'll pay more for ram and you'll have to buy it if you're not using it already. it's also a more expensive board.
if you want to go the pc-133 route go for the a7v133. it's about 40$ cheaper than the ddr board and you don't have to buy new ram either.
you can get either mobo and an AMD 1.33ghz 266fsb chip for under 400$
