Consider the used market, there are some deals to be had on Craigslist and E*bay at times (see item # 200026851250, looks like a stout steel frame if its big enough), just an idea, no affiliation.

Also, high quality Nitto brand drop bars can be had for 40 bucks on the Soma site that dd74 posted, and elsewhere on line. You'll want at least a 44 cm width given your size.
Good luck on the search and the ride.
