exiledemulator: Model F310 I was very fortunate to find it at Goodwill for 3 dollars not sure how much on ebay or anywhere else but new their expensive. Although, I wouldn't recommend playing Metal Gear 98 with it, its very stiff. Otherwise with Ion Fury its very smooth. I can imagine its probably frustrating with a mouse. I hope you can find one cheap.
In fact the Logitech mouse is very good and works perfectly on the Ion Fury, in fact, the Ion Fury was designed for the keyboard + mouse. And I don't see any problems playing with a mouse, as long as it's good, the point is that sometimes it gets tired, even more so for me who played shooters on consoles for years.
I use my Xbox 360 Gamepad from time to time, but it's a 5 year old gamepad that is already showing its age, hehe, so it's time for a new one. Here in my country, this model costs 32.91 dollars, which in our currency (REAL) is equivalent to 170.00. Definitely, Brazil's money is worthless. =(
Thanks for answering! \o
