JensonUSA has LX cranks for 100 bucks on clearance. That would work very well, though you may not need any of the stock chainrings, depending. I have a TruVativ stylo singlespeed on my 1x9. It comes with a 34 or 32 tooth ring and a bashguard, but no granny bolts if you ever decide to run a traditional drivetrain setup. No complaints so far.
