Until September 1, the current version of SQL Prompt is free. The next version (v3) is now scheduled for release September 28th. The price for v3 will be $195, BUT, you can get a pre-order discount price of $99. You must order before v3 is released (“no exceptions” I’m being told). To pre-order v3, contact Greg Tillman at greg.tillman [at] redgate.com, and ask him for a pre-order quote. There is no public URL for the pre-order special.
If you have some ideas or feedback for v3, post them in the forum at http://www.red-gate.com/MessageBoard/viewforum.php?f=44.
