I had problems with a couple of broken spokes recently, too. I broke one spoke, no problem, just ordered some replacements, but it was on the rear wheel on the freewheel side, and I had no way to get the freewheel off to replace the spoke. Friend of mine had a tool, we tried working on it by turning the tool and using a chain whip, couldn't turn it no matter how hard we pushed on it. Took it to a bike shop and he had it off in 10 seconds. Turns out we shouldn't have bothered with the chain whip since all you have to do is turn the tool while holding onto the wheel. He put my replacement spokes in and adjusted my hub, and I was out the door for $20. I did my own wheel truing, and the bike is running great. I've also ordered the freewheel tool which should be arriving Friday.
