DSL speed for dial-up

I have come across to two companies like netzero and proxyconn that offer this amazing dsl speed for a dial-up which seems to be to good to be true. netzero is $14.95 and proxyconn $8.95. I don’t mind having an internet provider that doesn’t have dsl speed as long as it’s a reliable company with good business practices. What do you think about these two companies? Should I trust them? At least price wise?
