For my obligatory update: I ordered the 6141 from Amazon last night. Saw Woot's deal this morning. Also woke up to an email from our landlord saying they'd have Time Warner come out today and put in our own cable connection at no cost to us. I suppose I'll keep the modem when it comes, because I'll probably need it in two months when we move out of here.

Thanks for the recommendations, y'all.
