Yup - I agree - they're simple and reliable and the Super Ferrite is a great little pickup.
I just sent my '85 mahogany Patriot to a buddy in Colorado who wanted to learn how to play bass.
I've owned most of the US-made Peavey's at one time or another (including your '90 Fury), but I've been on a selling frenzy since I lost my job. I'm down to just a small handful now: The Sarzo, Axcelerator, T-45, Foundation, Koa Unity & Forum.
The US Peavey basses are all pretty reliable instruments. The Sarzo is never leaving - I thought it was gaudy and kinda stupid looking at first, but after playing it, I fell in love with that thing.
