Most 3D televisions can be switched between 3D and normal viewing, which means you do not need two televisions, one for normal viewing and one for 3D. You will need to wear special glasses when you are watching the television to see the 3D effect. Without the glasses it does not work and in fact is not good to watch.
It is worth looking out for good 3D TV deals as with the regularly introduction of new 3D models, there are always some around.
I recently saw one deal for two pairs of glasses and a blu-ray 3D DVD player for only a few hundred pounds more than the cost of a normal television of that size. It can also be worth negotiating, if there are no deals or discounts see whether they will give some extra pairs of glasses for free or something like that. Many retailers are anxious to make sales and so it is worth taking advantage of this.
It is possible that as 3D television becomes more popular, the prices may go down.
However, if you are upgrading your television it is worth thinking about because this trend may take off quickly and you may not be able to afford to upgrade your television again so soon.
It is worth going in to a shop which sells 3D TVs and asking for a demonstration.
They will be happy to let you try out a pair of the glasses and put a film on for you to have a look at. If you have not seen many films in 3D or are not sure how you feel about watching 3D television then this is a good way to find out.
