Need your opinion about 5.0 surround sound system

I have a Panasonic S35 dvd player and Panasonic HE75 av receiver. And I would like to get a 5.0 sound (about $300-$400). I think Eltax is good at this price range. And i would like to hear your opinions about Eltax MovieMaxx 5.0 pack. I'll use it 50% of the time for music listenning(in stereo mode) and 50% - for movie watching(surround). Is it good for music listening ? Does it need a sub or front speakers are enough for bass (My music preference - electronic music such as techno, trance and drum'n'bass) ?

Are there any alternatives to Eltax at this price range ?

P.S. Sorry for my awful english.
