There are still many Windows 7 laptops available, new in the box. Check Amazon for Lenovo and HP. Both have units either direct or from resellers. My wife just got a Lenovo E545 with Windows 7 64Bit Professional preinstalled. Priced about $400. It does come with a Windows 8 disc (we ditched that one). You will find all sorts of setups that will have 4-8 gigs of RAM and hard drives of various sizes. YTour budget will determine what you wind up with.
As to your connection via DSL, don't feel badly. My buddy in central Wisconsin (CenturyTel) gets under 1 meg and has a powerhouse of a laptop. He connects to the router with WiFi, btw.
If you are at all mechanically inclined, then building a desktop BUDGET machine would be an option. You would have to either have or buy a new Monitor and keyboard+mouse. Total cost in the range of $500.
Hope this helps you.
