I got CS3 premier (the whole porduction suite actually - around $1000) and I will say that it sucks balls big time. It's supposed to be the best but it's typical Adobe crap. Don't get me wrong, Adobe has some sweet software. They've just been slowly slipping over the last decade with adding new usless features to the same program and giving it a new name.
Anyway...it's first major flaw - Oh, you want to edit MPG's? hope you don't need the sound...yea a known issue they won't resolve, but they will give you a conversion tool to convert your MPG's to some other format it can read.
We bought this for putting together some training video's, they wanted something as close to pro quality so I recommended this...We are now using Windows Movie Maker 2 (free download), it works (1 point already better than Adobe) flawlessly (2 points), it's free (3) and exports to MPG or WMV (4) with a zillion different codecs to choose from.
I called for support on CS3 and they gave me the run around - so I gave up. Called again about a month ago and now they're wanting me to upgrade to CS4. BTW - I have CS3 photoshop - but I still use photoshop 5.5 because it does everything nearly identical - and it's just faster. Really I have yet to find something that CS3 does better.
Also Macromedia software went to crap since Adobe took them over. Dreamweaver CS3 too sucks balls.
Sorry for the vent...it's bad enough that software companies sell the same software in different packaging with no upgrades, but too often they make things worse than they were to begin with.
