At my company we've used Jaspersoft and Pentaho and at various times paid for commercial licenses in JasperSoft's case to get support and some consulting (which we only used once) and in Pentaho's case to get a bug fix patch faster.

Both tools are relatively cheap, you can expect to pay around $10K per year if you want the commercial version of the full suite and are very developer friendly. They both use Java extensively, so you have to be willing to have that in your environment.

I would add one more tool to mix - MSFT SQLServer 2008. The standard edition (about $2K, I think) comes with a the full suite minus the data mining tools. The reporting tools are on par with what Jasper and Pentaho offer and the Analysis tools are very simple to use and allow one to use Excel as a front end interface (which is what you end users want anyway).
