I am assuming the 50 hrs of access is from the DSL company? It's fairly standard for DSL companies to give you a certain number of hours of dialup access in addition to your DSL. The thing is if you explain to the the situation, that you are just waiting for their peopel to hook things up, they may cut you some slack and give you unlimited dialup until the highspeed line is hooked up. It can't hurt to ask anyway.
If not, maybe they don't have these in your area, but around here there are companies that offer free dialup internet access if you use their special browser that show you lots of banner ads. It's kind of a hassle for regular surfing cause it makes your available viewing area smaller, but if all you need is access to get your email it would work.
50 hours though really should be enough time to get download and upload turns. Unless you are in a LOT of games.
