Simba instead of SCAR. What is your opinion about it?
Imho it's much better than SCAR (3.23). You have just as many functions and procedures as SCAR, plus some more!
And you have the 'Update Now!' button instead of reinstalling it each time one tiny bug is fixed/one procedure is updated.
Only downside is that it doesn't have a Bitmap or DTM editor yet (As of 7th of June 2010), but that's being worked on right now (afaik)
