Keep in mind you do get charged a "modem rental fee" or whatever, and in most cases its $10-20 dollars monthly. For you that might be worth it, for others who already feel like their ISP is a sham and charging way too much, it might cross the line.
I took the other approach at home. Just bought a new $175 router, which solved my "issues" (old router was crashing with heavy use). At home however, I have plenty of "fart around" time.
