Well, I think I found an even better option. I've been very happy with the cables and speaker wire from monoprice.com, so I think that the components should also be up to the same high standards.

This is essentially the same as the other two, but only $23. Since I only want to use two pairs of speakers right now I can leave the impedance button off and it will act only as a switch. My Onkyo 805 shouldn't have a problem handling a 4ohm load and so I should be fine. If I get speakers for another room, I will have to start using the impedance matching though.
