By all accounts, the fit and finish of the Studio 5 series is a little rough. The plastic outrigger feet are supposed to be a bit weak for their purpose, and look at the drivers in the shot below - obviously, the designers are not trying to make a visually stunning product. On this model, the budget was not increased to make the details look good!
So, knowing yourself (or your friend, in Pogre's case), consider that.
If you like things clean and pristine, the Studio 5XX's are not a good fit. If you have a "utility" attitude about such things, these are perfect!
