Ive been using gmail for things but recently started using outlook.com which I find is great. Main reason for it is because of moving to windows 8 on my tablet and desktop pc plus laptop.
Im going to look into having my own email if I can get one cheap enough.
If you went with FastMail - and assuming Talk21 support IMAP - you could use the "Migrate IMAP Mailbox" feature to quickly transfer all of your e-mail over while keeping the exact same folder structure. You would be up-and-running in less than an hour.
Own domain or Gmail. I have been using Gmail for years, since it was invite only
