The ones for home use typically don't have great resolution, maybe 5mp if your lucky. They also tend to have focus issues due to the curve in the slides (personal experience). And unless the scanner has ICE technology, you wind up with a lot of post-scanning touch-up.
What I'm leading to is maybe for only 160 slides, send them out and have them done professionally. They compensate for all the above and provide high res.
If you don't car about any of that, I have a small manual one that works pretty well if you care to borrow it. 5mp California area.
