I run bantams and pheasants in chicken cups all the time with no extra effort. 
My advice would be to learn as much as you can about incubation and the how's and why's of it. A person needs to really understand it first and then learn by doing it. Been incubating eggs my whole life and learned through trial and error long before the Internet. You have a great tool and there is lots of advice and opinions on the net, some good some bad. Decide what you can spend and how dedicated you want to be and go from there. I would also weigh into the initial purchase, of where you picture yourself in a year or two. Incubating is addictive and a lot of fun, but work too. So, this may make you want to spend a little more up front and get a good start.
