You might want to try using a site that provides used electronics, it's a really good way to get some nice stuff without paying full price. I would suggest using http://www.teknetelectronics.com . They recycle a lot of industry stuff that is in really good condition.
I would suggest using Movavi's video converter. You can convert between pretty much any format and it's really fast. Great when you have lots of movies. You can also edit your files to keep just your favorite parts.
