Canon GL2 -This camera have 3 CCd´s one for each color and gives you the standar resolution lines for NTSC (720X480@29,97fps) it is the best for your home videos.
JVC GR-HD1 -This camera can record in HD format (and the standar NTSC) HD 720 (1280X720@30fps) and HD 1080 (1920X1080@24fps) this formats are excellent for postproduccion, even if the final video will be down to NTSC
Sony DCRVX -This is a lovely one -I have one-
also have 3 CCD -one for each color, record in NTSC, HD 720 and 1080 a great Camera. good system and have a very little lens distortion
Anyone of the 2 options with HD would be my option, in addition it is becoming estandar so if you can be advanced to that in a pair of months that would be an advantage
Sorry my english it is not the best, i hope you understand me
