For that power level and budget, any generator in that class is going to be LOUD. VERY LOUD. Of course, loud power is better than no power in a natural disaster.
But, if the generator is to be used for regular duty (construction, commercial use) the noise will get to you after a while. Running a long cord helps, but you'll get voltage drop if the extension cord is too long. Also, if you're using it at a jobsite, OSHA rules require a 5kw or larger generator to meet specific standards. I think having G.F.C.I. and neutral bonding are necessary, but don't quote me on that. Check with a dealer who sells generators to builders or contact OSHA to confirm.
Next, are you sure you need 7-8kw watts? What types of tools/equipment/devices are you going to operate? With a little creative power management, you can maybe get by with much smaller unit. For example, if used for home standby, keep the 'fridge plugged into until you want to run the microwave. Then plug the 'fridge back in after the food is cooked. Even a 2kw unit is plenty to recharge cordless tools.
Finally, a traditional generator runs at wide-open-throttle to make 60hz power. That sucks down a LOT of fuel fast. A modern inverter-style generator can make power and change engine speed depending on the load. Light loads=lower engine speed, less fuel consumption, quieter, longer engine life, etc. Of course, they're more expensive, but deliver a lot of great features for the money.
Caveat: I work for Honda, but the preceding was my opinion alone.
