Canon Gl1 Minidv Minidv Hd, Or Avchd For New Camcorder, Or Stay With Gl1??

Minidv hd, or avchd for new camcorder, or stay with Gl1?? - canon gl1 minidv

I get a new camcorder that is smaller and easier / faster for video editing ...
I currently use a Canon GL1, but it is too large for Cary, and the snow ..
I do not have 100 tapes and tape-editing is a pain, so I have about the use of AVCHD and Final Cut Express is one for editing, so I know it is compatible, but I've heard that the quality is not so good is

The quality is very important and I want to move into a high-definition camera, does anybody know what is best? or it makes sense to keep the GL1?
