Totally agree with Graham, the 32" model is far superior, it got better speakers too (the 28 model uses one fullrange unit, while the 32 model got a tweeter unit and a midrange/bass unit). And most people don't know this and expect the 28" model to sell at the same price as the 32" model. The 32" model also got 100 Hz technology (being an avant chasis).
So, to sum up, only buy an 28" model if it is very very cheap. Othervise, go for the 32" model. What kind of stand have you considered? There are some to choose from. Have a look at lifestyleav, they probably got some.
