Automagic webapp testing tools

[<inflatablekiwi () gmail com>]

Hi Folks,
I currently use SPI WebInspect for as part of a process for vulnerability assessments/pen tests on different web 
applications. The license is up for renewal soon and before re-purchasing, I'm wondering if anyone on the list has any 
real world thoughts/experiences on how it stacks up against some of the alternatives like 

 - Watchfire Appscan
 - Kavado ScanDo
 - Any others I've missed

Any list member’s thoughts (on or off the list) or pointers to good product comparisons for these would be much 
appreciated.  I'm more of a believer in manual testing myself (yay Netcat and WebScarab!), but I also see the value in 
these sorts of tools.

Ta,
IF

p.s Also as a totally random aside - I've recently been reading a couple of different security vendors pen test reports 
for similar profile web sites and I'm amazed by the analysis disparity on the same simple issues (like track and trace 
verbs being enabled - ranging from "Extreme Risk - The sky is falling - you will be owned now" to "Low risk - disable 
these verbs and move along").  Just saying.
