Depends what you want to do with it, for basic Youtube applications any version of Vegas will work ($50 one) but if you are looking to eventually get into the professional industry of content creation than skip vegas all together and put the time in to learn Premiere Pro, it comes as part of the adobe creative cloud service so you get photoshop and after effects etc with it, it links into all other adobe software, and it looks better on a resume. It's also a lot cheaper. Sony Vegas Pro will cost a few hundred, and than a few hundred again when you need to upgrade. Where as the creative cloud is a small monthly cost that lets you always have the most up to date version; which I mean, you're also getting ALL the adobe programs for that cost
