I second Christoph- I use this same version of PL/SQL Developer and have adopted it as my favorite. It can be configured to leave a much lighter footprint on the data dictionary than some of the heavier featured tools, too, especially if you have numerous developers and DBA's all utilizing a GUI to work all day... Less raved about, especially with Grid Control's OEM, is the stand alone OEM from Oracle that came with 10g. I've got a few developers and DBA's that have this as a second GUI window into the database- especially when I have someone come to me, frustrated that no one has installed an agent on a brand new development database, I can steer them towards this to give me some breathing space. Just install it as part of the 10g client install and it will give them a quick window into sessions, long ops, configurations and a light weight tool. Nicest part is that it's Java, so if you have a problem, just kill it from your task manager, it could care less!

It is light weight, intuitive and low priced. It has a query builder, which is good for less savvy users. You can easily copy query results to Excel. It even has charting capabilities.
