Cannot reccomend http://digitalpigeon.com more highly! Its the first file-transfer service I decided was worth paying for. WAYYY better than hightail and wetransfer. Transfers to and from are super fast, like SUPER FAST.
Like hightail, you can setup a dropbox esque page that allows clients to send you files via your account.
Wetransfer is absolutely fucking horrible (maybe its just in Australia), any time I have to download a file a client has sent me via wetransfer takes HOURS. Hightail is not much better.
You can choose file server location (asia pacific, america, europe etc) and its pretty damn cheap. I pay ~$30 AUD / month and get 20gb of transfers in and out, extra GB are charged at $0.70/gb. So its pretty affordable for me as a freelancer.
And what best, it looks fucking sliiick when you send a file using it.
(oh and also, the developers are super active. I made a suggestion for an improvement and it was implimented 2 days later. they have a voting system accessable directly from the main page that lets you suggest features and vote on new ones. which is a big tick for me)
