Ohnofiasco,
A dedicated arm for SPUs is the way to go, IMO.
I like MintLPs. I have a few of them for various arms. In general, I prefer Wallytractors because the inscribed lines on the mirrored surface seem a bit more precise, and the mirroring is better, for reduced parallax, but you can't really get them anymore.
Ken Willis' Accutraks are also good. What I like about them is the lines are on the surface whereas the Mint's are beneath a layer of glass. But the Accutrak lines are even fatter than the Mint, which isn't much of an issue if you take the time to make sure the stylus comes down in the center, and they're not mirrored.
