IMO if you find a used les paul studio for $500 to $800 it will always be worth that much if you take care of it.
Ditto on a standard...you can get a nice used one for $1200 to $1500 and it will always be worth that much.
I bought a used les paul studio for $500 and put the '59
PAF pickups on it (another $200..but I already had them, they were in a flying V) So, I have a really great playing and sounding LP for $700 total. It has
the fireburst finish and gold hardware without binding and I really like the look of it.
If you like the look of a binded les paul body with a MOP gibson logo on the headstock then I say cough up the extra money on the initial investment to get the standard. If you keep it 5 years and play it only one hour a day the $1000 difference translates into only .55 cents an hour.
Is it worth .55 cents an hour to have the LP you want and not the one you have to settle for?
To me it would be.
Like I said...it will hold it's value so you can recoup your money if you ever decide to move it on down the line.
If you like the non-binded look of the LP studio and like the tone then I think you should save on the initial investment and get a LP studio.
