There are a number of alternative 50Hz refresh rate TVs currently available that you might want to consider including because of its better review score, the Hannspree AD40UMMB.
If this television high frequency rate is too slow for you then you might want to look at the JVC LT-32C461 (£154.99) (60Hz), or the Philips 24PHT4000 (60Hz).
