I bought a Sony CX440 refurbished from Amazon for about $160. It has 60 fps and 1080p and the quality is pretty good in well lit situations. At nighttime it makes my walls look a bit green though. It's great for the price. Otherwise I hear Canon makes pretty good camcorders.
Oh I think PewDiePie used that one for his daily vlogs. A small camera like the powershot is good if you plan on doing some outdoor vlogging. I'd suggest getting a camcorder though because they can record for longer and are meant to take video unlike cameras. Also with that money I think you can also consider a DSLR like the Canon EOS Rebel DSLR which will basically give you the best quality, but will be very heavy and hard to carry around.Thank you! I'm looking at the Cannon Powershot g7x , but I'm going to have to save up for a while.
