Sending large files, videos etc

Just wondering if anyone has sent large files ov er the internet - say using DivShare or YouSendIt for e.g.? If so, could you tell me what your experiences were, and who you would recommend? I'm looking for a place to store and/ or send my large files to someone else so it doesn't crash theirs or my email system! Would it make more sense to get a webhosting thingy to look after everything for me at the same like - like GoDaddy or SiteFive. I've heard of all these sites but would prefer recommendations.
