I pay 24.99 a month for Road Runner in Central NY, I can upload like a wiz and my download speed has maxed out at 1.4 something megs a sec downloading from File Planet, So about you're question uploading on 56k, Simple, Don't. unless you plan to upload a 1 meg file in 15-20 minutes. I can upload a meg in about 6 seconds, So, get the DSL in you're area for about 10 - 20 bucks more a month, it's worth it in the long run, I had DSL before and when it went out I had access to the 56k server, It was worthless, and now DSL is worthless for what I have now, So if you get DSL/ISDN/Cable you will be in heaven.
