Good OCR options?

Is there a good OCR program that can convert my old government science papers into nice electronic replicas?
When I did small projects like this 8 years ago I used an OCR program, clipped out the graphics one by one, and just kind of pasted it all back in PageMaker. Surely since those early years something has come out that has automated all this tedious work.
I'm hoping to thin out my paper library (and make things easily searchable) as well as share some of the stuff on my website with other people in the field. Ideally the end result will be PDFs.

First off, most OCR is still pretty bad. It's really hard to do segmentation well.
Currently, one of the industry leads is Abbyy. The app, FineReader, is fairly well put together and is fairly unsurprising in terms of UI. Expect to pay through the nose for PDF output. As far as I can tell, they license from Adobe for PDF generation.
ScanSoft is one of their leading competitors and their engine is OK, but they've clearly been asleep at the wheel in terms of features. They do have PDF in their feature set.
ExperVision does decent segmentation, but at the expense of some extra errors in the output. Their PDF output is an add-on and pricey. I'm also not impressed with it.
Its been a while since I looked at the Iris engine. It was supposedly pretty good, but I don't recall if it has PDF output.
Most of these packages also include RTF output at a minimum, sometimes full DOC output.
SimpleOcr is awful. Don't waste your time on it.
My experience comes from writing interfacing to run these engines in an engine-neutral way.

Our company is getting ready to lauch OnBase, whose OCR component is called Verity. Anyone know anything about that?

Setting the scanner up correctly is crucial, to avoid many errors. Black and white scan (not grayscale or color) if at all possible, tweak the threshold, 150-300 dpi (or more, if it's really small text), etc.
It's not cheap, though. It's something like $400 bucks without an upgrade.
