I talked about it a few pages back, but I took a punt on a cheap Pro-style controller from Amazon for £17 before Xmas and have been impressed with it. I wanted a 'proper' controller for the Switch I was buying our son - figured he might end up preferring the JoyCons (he does) but that I would prefer the 'real' controller (I do)
I've not used, or even seen in the flesh, a legit Pro controller, but I come from using Xbox One (and 360) official controllers and this one was, whilst not quite on the Official Xbox level in terms of quality, very good nonetheless.
Anyway, it was this one, was on offer when I bought it but still cheap enough:
