help entertaining people

I have a gameplay channel on youtube and I love doing this, and hopefully entertaining people :) but at the moment i'm on a 30 day trial of Tech smith's Camtasia studio 8. this system is perfect for what i'm trying to do! but after the 30 days, the program costs $300, which is 200 pounds. the other 60 pounds I want to use to get a dazzle DVD recorder hd so i can add gameplay from my PS2 to my channel which will hopefully be something people will love! 
so if you could help me out that would be totally awesome :) every little counts and i'll appreciate any help! I'm also trying to do some babysitting on the side to save up, so if that works, the target will get lower and lower :)
