Normally a router will also be faster on its cuts and rapids, the milling machine will be more usefull. But if flat stock is all that you need to work with then a good router is probably the ticket.
The main thing is to research very good exactly what your trying to do & exactly what eachh machine you look at will do. When yuo first get into this stuff there is so much going on its very easy to not understand everything that is in front of you ( like what the machine will really do).
When yuo think yuo have what will work for you post it in the thread and get others feedback on your choice because when your new to this its very easy to over look something that may be important, or get misslead.
Also searching U-tube will give you great feedback on any machine your looking at, or any work your trying to achive. There is a lot of video's/info there that can show you alot about what your getting into.
And remember it will allways cost more for tooling, measuring equipment, setup equipment, software and such than the machine will cost. So the machine price is only a small part of what you need.
