Perhaps the "cheapest" way to get multi-pole switches comes in the form of one of the switch boxes available at computer stores. A 4- position DB9 switch box will generally give you an 8-pole 4 position rotary switch and a nice little box for just a few dollars. Moving up to a box with more ports gives more poles. They may not be the best switches available, and their characteristics at RF are open for debate. But, they are available, have low cost, and they work.
And you get a box to go along...
