Fes, if you haven't already done so, try a search for *reviews* on Google and at this forum (use the search icon at top). You'll find comments related to the Edirols, which I haven't heard, as well as comments on a variety of other budget monitors (under $300).
About buying online, remember that you can always order a couple brands (your final contenders) and then return your least favorite. No one really wants to do this, of course, but many of us do simply because we need to hear a product in our own home studio before deciding. I do it all the time, but I always buy one, in the end, from that online store, just to be sure I don't waste their time and money in the end.
Good luck,
J.
