You should consider the brand and the reviews. Unfortunately going into the store you only get a few opinions and that is the opinion of the people who work at the store. Your best option is going to be to look on Amazon not only will you have the best selection, but you will also get the best price and being able to read all the reviews and the product before purchasing. Also, keep in mind that you get free shipping and returns with Amazon so I consider this to be the #1 option.
