I'm actually a big advocate of the SA series. I have a lot of Ibanez guitars including a number of high end ones (Prestige and other), plus I have an SA160 and an SA1260. Oddly, the SA's get about as much play time as any of them. You didn't mention which SA you were considering (used or new?), but here are my observations:
Neck: I think the SA neck profile is great. No, it's nothing like a Wizard or even a Wizard II ... it wasn't intended to be. As noted, it's much more like a traditional strat neck (or a JS
neck). Frankly, the Wizards don't appeal to me much anymore: simply too thin and "edgy" -- hard to explain, but my taste has just sort of evolved away from them. That super-thin, super flat Wizard profile seems like overkill now.
Bridge: I like the SAT bridges. I replaced the tuners on both mine with locking tuners (not really essential as the tuners are pretty good-- I just had some around and put them on), and use Big Bend nut sauce on the nut and saddles. With normal use (no huge dive bombs), it stays in tune fine. While I have a number of locking nut guitars, the non-locking SAT bridges are a big relief.
Pickups: The only major negatives on the SA's are the electronics. Yes, the pickups are harsh and lacking in character. I also had to replace the input jack.
I use the SA160 as my "travel guitar" since if it were lost or trashed, it wouldn't be an irreplaceable loss. I've played it live lots of times, and been very pleased.
So in summary, I think the SA160 is a great value in its price point. Used ones can sometimes be picked up for less than $200. The finishes are very attractive: Ibanez has been getting better and better at putting nice quilted tops on their lower line guitars. For a mahogany body, strat-style guitar, I haven't run across anything else that seems comparable. I don't know anything about the new Prestige SA, so I can't comment on that one. Also, it's probably true (as discussed in other threads), that the Korean products may still be lacking in consistency as compared with the Japanese models. I haven't been through enough of them to render judgement on that point, but so far I've had four SAs and haven't run across a lemon yet.
