I'm pretty well decided on an AMT Labs Legend Series II pedal for an uber small den setup for my guitar and wondered what are some decent inexpensive powered desktop studio monitors that would work well with it? Seems like there are a ton of different powered studio monitors-- what are some good ones that would fit the bill for my needs? They don't need to be any bigger than a bookshelf style speaker, and I would only need one since I'm not running a stereo rig. I figure this might allow me to get a nicer monitor since the nicer ones are usually priced per speaker, not per pair. So what say ye?
