It really depends on where you will ride the bicycle, how often you will use it, if the bicycle be used for competing or pleasure and your body type. One more thing to consider will be the budget you want to invest for the bicycle.

More than just the budget you should also consider the purpose of the bicycle - pleasure or compete and your body size. If you consider it for pleasure my suggestion would be to search online the different models and have a look of them into a shop, try the bicycle and then find the best price.
