I have my DSL and VoIP with Speakeasy.net. Had them for 7 years (DSL for 7, phone for about 2) and haven't had any issues. They were bought by Best Buy last year, but so far service is still good. They support Windows, Mac and Linux and don't give a wet slap what you use the connection for-- as long as it's not a pr0n site or an IRC server.
