I'm not a piano player but a piano tech.
The good news is, 48" is a good size for a vertical ("studio" size...don't get nuthin' smaller) and 1300 is a GREAT price(!) for a studio, espcially with delivery and two tunings included.
The bad news is, i think it was made by Samick and that ain't great, especially a few years ago. You might ask your piano player friends how they feel about Samick uprights or, better yet, get one of them to go play it.
Normally it's a good idea to get a tech to check it out but i assume if the dealer is a friend, you don't need to worry about anything structural being wrong with it (?)
By comparison, you gotta figure something like a used Yamaha in that size would be at least 3 grand, up (and up a lot, i should add).
You might expect to hear piano players bitch about it but i'm always amazed at how good a good piano player can make a crappy piano sound.
