I've got a line on a PB 2400- but it's all apart in a box. Owner says he thinks it's all there but.... I don't mind a project but just wondering how tough these babies are to piece back together. I've been inside several PBs in my day but I've also heard that the 2400 is particularly tough to work on. The only one I've ever seen is this one so I've got nothing to compare it to as far as a working unit goes.
