Stress of buying new gadgets

Anyone ever feel lost when trying to purchase some new gadgets which you have no experience with it? It could be stressful, to both usage and the wallet. I just bought a harddisk media player. Being new to such devices I have no expectations, except to be able to play all my videos. I went to browse at all the different type of such players. Most of them are of unknown brands from China. The sales person doing the demo do not sound local and they kind of avoid specific questions, probably they have no answer. They gave the most common features, plays all medias, can do streaming and watching online videos. After over an hour of loitering and decision making, I selected one which is cheaper, with the features I am looking for. The rest are considered value added. Once home, I connect it to my TV. Looks good except that the screen size seems wrong. Doesn't matter. Test a few video files it works. Pull out my network cable and connect to the player, it could access net videos, hosted on a china website that is like youtube. If it is china website, expect chinese contents. There are some movies and drama selection. Some of them are laggy. Looks like you need luck. I could also stream drama to my harddisk. Tried to pop in my 3.5 harddisk to the casing, it seems I have some connection difficulties. Either the casing doesn't fit well or I need to adjust my harddisk. I plug it as external for time being and tried a mass selection of some videos. Most works, except for some AVI, FLV, MP4 they can't be played or no sound. I understand that with all the new codecs coming out there is no 100 percent to. Now that I am kind of familar with what the play could do, I am tempted to go for one that could surf to youtube. Maybe in a few months time....
