What i would suggest before making the move and if you haven't done already is to monitor your routers traffic (type)
You may also, look at something like a Dual wan router (get TWO adsl connections)
If you have alot of mail traffic you can simply create a load balance policy to route that traffic via the specified wan port
Most dual wan routers have QOS as well ;
http://www.draytek.us/ent
The draytek 2950 offers dual wan support (you would need two adsl MODEMS if you wish to connect to adsl lines to it) it has 5 Gigabit ports so you can uplink it to your GB ethernet ;
it offers a robust content security management, load balance, qos etc
I am sure you can easily get a 2nd adsl line and then you can calculate the cost to see which solution is cheaper.
hope that helps

Looking at anything Fiber will be more expensive then a dedicated T-1.
Couple of options. In your area, you should have a cable/or satellite provider. The reason I suggest that is some cable providers can install piggybacks to help a smaller sized business instead of them making the jump to a dedicated line.
HOWEVER, if you are expecting to have a large flow of data or graphical data passing in and out of your business, you will want to go for a T-1. With 50 employees, you are on the verge of a mid-sized bandwidth user. A T-1 will allow your company to grow since you already have the GB switch internally.
