^ I'd respectfully disagree with that. the quality of the LP studio, IMHO is not way below that of a Standard.
The studio was created to be a stripped down, no frills version of the LP standard, sans binding and etc.
The main difference between studios and standards are the pickups and binding. Apart from the binding, everything on the studio that may be "sub-par" can be upgraded. From my own experience, i actually prefer some studios over the standards. Especially the newer LP standards.

here's a good demo of the studio VS a standard, yes i agree that the standard sounds better in the video, the new pickups (post 2003) in the standards are BBs i believe, while the studio has ceramics (490/498). The ceramics are in no way inferior pickups either, considering that the standards were using them until 2003 and now i believe that the les paul customs, classics and supremes also have them.
Studios are definitely pretty good for the $. the 90s pieces are exceptional.
Also, newer standards come with tonepros hardware, easily obtainable upgrades which can be had on a studio as well (or faber hardware)
