Quality is not great, but not complete garbage either especially for the price. You can get just a neck (strat & tele styles only) from universaljems.com REALLY cheap. Brian's (not me) a good guy, he'll hook ya up.
Plastic nut pre-slotted, frets are okay, usally 12" radius on the above.
The necks for the saga kit for PRS style aren't available, only the S&T style are.
Hope it helps.
