I always read the reviews by other users on websites like Amazon.com and I try and read them all. When I find negative ones I look at the length of time between purchase and review write up and most of the time those reviews are writen right after they have received the item and they haven't learned how to use it yet. I used to work in a call center where I walked offices through fixing computers and network issues in their office. Whenever we had a new client they would call in complain about the sofbtware not working correctly. Patience...they eventually got it. It was user error most of the time not equipment error. I think almost all electrical/computerized equipment has some quirks in the software. But there are usually work arounds or patches to fix issues. Good luck on your choice.
