I use MAGIX Movie Edit Pro a lot. The last one I got was 15 Plus, but there's a newer version out now I believe.
It's not the best program out there, but it's worked pretty well for me over the years since I started using the programs. And if Wilsonville isn't too far for you, if you keep your eye on the Fry's Electronics ad you can usually find the programs pretty dang cheap. My first MEP cost me nothing as it was $40 with a $20 in-store rebate and a $20 mail-in rebate. MEP 15 Pro Plus was on sale for half off it's original price, so I got it for around $25 or 30.
And yeah, I think MEP has a trial. I'm not sure what the trial entails, probably just a time-limited version with less features or something.
Though I do wish I could find a decent, easy to understand, cheaper special effects program so I could make lasers, explosions and such. I'd love to find one... ><
