What have you heard about the old versions ? I think CS3 is quite good and if it had those so called problems in the past all the others had too, it's normal they are improving, I like adobe premiere and i've been using it since version 1.5 and you can always download a trial version and use it for 30 days.
I heard that final cut pro is very good but you need a mac for that and if you don't own one and do not plan to buy one forget about final cut . It gives you cs3 and sony vegas you can try both for free during 30 days. Final cut pro does not have trial versions either you buy it or not .
Peace out
