Without doubt the cheapest one. Kinda funny, TV2 Hjelper Deg did a test, and no one, not even the sales person from Hifi Klubben could spot any difference what so ever. Note that it also included a test by a professional consultant with the special equipment http://www.tv2underholdning.no/hjelperdeg/article2323104.ece
And we have still not even bought a flat-screen tv 🙂
