Re: 10 hives, how large an extractor?
Brad, I have a 50 year old motorized Kelley 4 frame tangential extractor. I would not hesitate to use it to extract from up to 70 colonies. It holds 8 shallow frames in a load and can spin them out in about 3 to 4 minutes swapping sides after about 2 minutes.
The average hive here produces about 60 to 80 pounds of honey. That works out to about 2 or 3 shallow supers. One hive will fill up the extractor 3 or 4 times. Allowing 5 minutes per load, each hive will take about 20 minutes to extract. Ten hives would equal 200 minutes or about 4 hours of your time.
I would get the Maxant 3100P motorized extractor or if you feel like you may get more than 10 hives, get the 20 frame radial. Your next question should be about honey handling equipment. You will need a 100 gallon stainless steel tank with honey gate and some basic gear to uncap the frames.

100 gallon stainless tank with honey gate
Uncapping screens for the top of the 100 gallon tank, uncap into the top of the tank
Plastic drip pan to set the frames on as you uncap them
Stands or legs for the extractor and tank
That is about as low tech as you can go while still getting the job done in a reasonable time.
