Block diagram tool?

[Seamus]

Good day.

In an attempt to actually produce some sensible documentation, I've been looking for a decent block diagram creation tool for use with Win7.

Many years ago, I used Visio for such things, but it has since been swallowed up, has a prohibitively high price tag, and I will want to use it beyond the 60-day trial period that they offer.

Does anyone have suggestions as to a decent free or low-cost tool for drawing block diagrams? Sure I can hammer some out in a basic drawing program, but I'd like the flexibility to drag elements around and move the connections along with them, rather than having to redraw every time.

Thanks!

I'm a Mac/unix guy, but the freeware vector drawing program Inkscape ( http://inkscape.org ) has a block diagram mode.
