Excerpt: I scan thousands of documents at the National Archive, and have been looking for a faster and affordable, large format type scanner. After checking HP, Epson, Mustek, and other scanner manufacturers with no success, I chose with reservations the Plustek A320. The reservations were the price and lack of 'name' recognition. Fortunately, B&H's return policy is a big plus in these types of purchases.
Pros: Accurate Color, Easy To Set Up, Good Resolution
Excerpt: This is a great scanner for the price, especially considering it's size. The only problem I found is that it tends to de-saturate colors, and if you try to scan something with texture (like leaves, or something like that) it tends to over expose and you loose all the texture, unless you put some sort of spacer to hold it about 3/8" off the glass. Once you do that, it picks up the texture very well.
Pros: Easy To Set Up, Good Resolution, Widely Compatible
Needed Repair while under warranty. Customer Service A++++ . Update later
8 June 2013
Summary: Had it less than a year. It was used sporadically. I had about 1,000 scans with it before the head locked up and it won't move now. So right now it has cost about 50 cents a scan. That's a little steep for me. Update: The scanner was still under warranty. About to return for repair. So far the customer service bests ANYBODY I've dealt with for a while. And by the way... I'm running OS X 10.8. Scanner Utility works.
Summary: Like several others, I was unable to install the driver on a 10.7 machine. I had a 10.6.8 machine, installed it, pulled off the application, and was able to get the scanner functioning. E-mail me at firstname.lastname@example.org if you would like to try the driver I found.
