Flow Chart IDE

I am looking for a simple Workflow IDE where users can visually create worflows. No background functionallity needed just an easy to use IDE for flow charts. Some basic geometrical forms, connectable with arrowlike lines, headline and text. If you got anything close to this please send a screenshoot/feature list or Video (I recommend Camstudio). Handling and features will give the edge over prize here. So if your IDE has autosnap, color palettes or whatever don't forget to mention it, esp. if you plan to overshoot my budget, which you are free to do, as long as your application overshoots my expectations as well. IDE prefered as a single class. Must be vb.net but if you feel more comfortable in C# simply use one of the free vb.net converters, e.g. the one from developerfusion. Only thing apart from any IDE functionallity you might come up with: You should be able to save and load any created flowchart (I'd prefere mysql for saving, but no necessarity).
