I own two Sony HDV video cameras that record at 60i and have been well pleased with the quality. As far as interlacing vs deinterlacing goes it all depends on how the video will be viewed or delivered (DVD vs Blu-ray). If what I just read is correct, you will see problems with panning shots if you convert 60i to 30p. If you plan on putting the footage on DVD then deinterlacing is not necessary. If you plan to upload a video to YouTube then you might consider deinterlacing the video. I have not noticed a loss of quality when I export clips to H.264 at either 720p or 1080p.
