I've had it with shitty bandwidth speeds...Is there a better ISP than RCN?

So i've been with RCN for quite some time now, i had them when i first moved to the Lincoln Park area a couple of years ago, and their service was great. I had them when i lived in West Loop a year ago, they were great then too. I just recently moved to East Rogers Park, and all of a sudden they BLOW.

I purchased the 20mbps package, and was really excited to get awesome gaming speeds, netflix quality, torrent speeds, etc. Everything was fine for a couple of weeks, then all of a sudden i started to notice the speeds drop drastically (below 10mbps, under half of what i'm paying for). Every time I call them, they tell me its outages and other bullshit, but this has been going on for MONTHS now. Now i'm lucky if i can even get 5mbps, and i'm just pissed at this point and want to go somewhere else. I've probably called them over 10 times at this point, and gone through the same unplug, plug, speed test procedure over and over again.

I know all of the evils that Comcast is about, so they may not be an option...but has anyone had any great experiences with another ISP in the Chicagoland area? I cant seem to find a good comparison site online. Thanks!
