When something craps out in the dual ballast, you're out 2 lights in a sense. Conversion bulbs are cheap, replaceable, and don't complicate a reliable process.

It would depend on the cost some. I got my 400 watt mh/hps ballasts for 30 dollars each. If one goes bad, there's about 1000 replacements on craigslist for similar prices.
