Ohhhh.....you're an inquisitive little dickens are'nt you , seriously, these questions have been asked 10 fold, if you searched you would probably find them in a single post for you to view.
As for how much, you are in Eire or NI? (I assume Eire, because if its NI you are using the wrong flag , but lets not get all political ).
In the UK, you can source a DFP for a touch over £50.
Will force feedback improve your times?, nope, it will make you slower to start with, but in time you will get quicker, plus you will have a more realistic experiance.
