Agree with above...
The SE line is manufactured in Korea and has a generally lower grade of "fit and finish".PRS has fairly recently started to add some of the PRS "signature" features like bird inlays and figured tops. They're pretty much exactly what you'd expect from a "student edition" - sort of thickish finishes, thinner, less figured tops on the one's that have 'em, no locking tuners, "PRS design" pickups, etc. Still, nice guitars
I recently bought an '02 Santana III - one of PRS's earlier attempt at a more affordable instrument and it's a wonderful guitar. No gold hardware or fancy inlays, nice but not spectacular top, etc. You can get 'em in the $1599-$1999 range (the higher end would have the 10 Tops). Unfortunately they're not all that common - it took about a year of semi-serious web watching to turn up mine. (The one here: http://www.ultimatesantana.com/PRS-Paul ... a-III.html
could be my guitar's twin.)
Not surprisingly, people tend to take good care of their PRS instruments, so real nice ones are not hard to find at pretty decent prices, especially if you can live without a "10 Top".
