I actually made a thread about this with about the same budget and these are the general response I got. My budget is slightly higher but here you go. So far i've read two reviews on the Eagle set and they actually seam to do quite well for the price tag that comes with them. If you can manage to get an extra bit of money I would definitely recommend getting the Swan M10s. They look beautiful and they are a great set of speakers.
