Always-On Internet For Cheapskates?

chuck writes "I like my broadband Internet access because of its always-on nature, but my usage doesn't really justify paying $40-$50 each month for hundreds of kb/s when all I really do is read and write email sporadically, light web browsing and IM. Are there any options for cheapskates like me to pay less for lower bandwidth (modem speeds would be fine) but still have an always-on connection for cheaper than cable or DSL? I have a $5/mo ISP that I use when I'm out and about, and my 2.5G wireless phone can give me internet access on a shoestring (with free evenings and weekends) but neither of those has that always-on quality. Any ideas?"
