HI,
from what I understand a radial extractor is the way to go!
you extract both sides at once, I have an older 10/20 maxant
I bought it used for under $400, found it on someones website.
So do some lookin b4 you buy something new, some poeple sell
there bee stuff for pretty cheap!
I was told and also have read in these forums that a 10/20 is
about right for someone with ten hives, but when your at ten and you've
had a great winter and everyone starts to build swarm cells, you may find your self with more then ten
thats my two cents
