Page 1 of Surround speakers TECHNICS????

I have been on the site www.dealtime.co.uk, enquiring about home cinema systems but im unsure about a few things.

They have a surround kit without decoder, but with 5 speakers, this package looks very modern and is only £100.00. The model number is SB-HT140. Does anyone know if this system is any good?

Also, I have a dolby pro logic television with right and left external speakers, but im wondering if i were to buy this kit, would i need another decoder, or would i run the speakers through the TV? My DVD player also has speaker ports, would it be better to use those ones?

Thanks

Bruce
