Yes i understand that you think 16,-$ is way too much for a part that also can be found for under 2,-$.
But also you say that you donĀ“t have enough knowledge or information to find the right part.
So there are two possible ways to go forward:
1. Just buy the part for 16,-$ that you know will fit and function because some other peope did the work for you so you can use your mpc in no time and start making music again.
or
2. Try to educate yourself more about the part you need by - reading the datasheet or the list on the page you linked, find out more about the actual failing part in your mpc, find out the resistance value and taper, measure the shaft length and so on.
You do have some measurement tools, do you? Surely you have because you also would solder the replacement part yourself, are you?
Then maybe also read the description on the mpcstuff website, maybe there is some technical details listed. Reduce the list at the website you linked to the products that fit the demand. Order that part, put it in your mpc and you can start making music in a little bit more time but you will surely learn quite a lot till then.
