Designing Interfaces with Balsamiq

In the last seven months I have the need of sketching a bunch of interfaces, but I cannot find a valid tool. I was a Software Architect of a big huge project, busy also on other smaller projects as project manager.

I need a rapid way to sketch use cases, to pass them to a very young team.

Web interfaces are not easy to design, and we was in a very weird situation: the team was forced to use DAOs, with no O/R mapping tool. So I need also to map some interfaces to a database model, to help them building the model and the view classes

After some search, I ended up with MS Visio.

MS Visio is great, but too difficult to use, doing training is hard and so I must discourage its use. Worst, Visio costs a lot, and it is not included with the standard MS-Office Tools.

Visio offers only WinXP look&Feel, which is not the best for designing agnostic web interfaces.

Thank you to a friend of mine, I have the discovered the BalsamIQ Mockup project. Let's see why it is a so good solution.
