It's a personal preference. But I would go with Honda or Yamaha.
I have two 2000is Hondas. At around 50 pounds each I can move them with no problems. Use one when don't need Ac and two hooked together for AC. I run a outboard gas tank with hooked to both. Will run 15-24 hours on one tank. That's less than $14 day at current prices.
