If it's Stoeger or Mossberg, then stick with Stoeger. They haven't been out as long, but they seem to have a better track record than the 930. I've personally witnessed numerous 930 meltdowns at matches, and I wouldn't wish that on anybody. I'm sure Stoeger has lemons also, but I haven't witnessed one yet.
The other thing to keep in mind is the "extra" stuff you'll probably want to do to whatever you end up getting. I'm talking about lifter work, opening the loading port, extending the magazine tube, etc. Plan on another few hundred for that...unless you plan on just running it bone-stock which is a perfectly fine choice.
