Let me start off by welcoming you to the forums. Please be sure to visit the FAQ (located in the 2nd sticky thread in the Anime Discussion section), which answers lots of questions you may have about this site, and about HK DVDs in general. 
Anyways, to answer your question, there has not been a version of Sugar: A Little Snow Fairy on HK DVD that contains the english dub. As to when there might be a perfect collection containing english dubs, that's anyone's guess.
