I recently used Remitly and found them very good. They seem to specialise in quick money transfers to non-first world countries. They support some of the smaller currencies which the major online transfer websites don't. And they get the money to the recipient's account very quickly at a low cost.
Mod: Added to referral system below. If clicking on referral link, and wishing to transfer to a country other than the Philippines, goto the bottom of the page and change the "Send money to" box from the Philippines to the country you wish to transfer money to.
