Buying a camcorder can be difficult. Do you want VHC? 8mm? Hi-8? Digital 8? Mini-DV? Then there's whether or not you want to be able to take stills, have firewire output to a computer, image stabilization, etc.
One can easily find themselves saying, "All I wan't is a basic camcorder to record random things." If that's you, this is your camcorder.
Though the picture is not digital, Hi-8 offers a nice clean picture that gets the job done. And since you can plug right into your TV or VCR, transfer to video is simple without having to store all your old tapes like you did in the VHC and VHS days. Being a Sony, you can expect a great zoom that let's you get nice detail from a good distance away. Add Steadyshot, probably the best image stabilizer out there, the ability to manually adjust your lighting, nightshot, and you have the ability to record in any situation.
Having sold Sony's for over a year, I can tell you the number returned due to dissatisfaction was minimal. Same for broken or damaged camcorders.
Bottom line is this. In the TRV-318, Sony makes a great camcorder that's not only easy to use, but able to take a nice clean video. And as long as you don't care about capturing the light flicker off a snowflake, you'll love it too.
