Oh gosh, how loong is a piece of string?
I have a TRV33 (Incidentally this does have stil limage capability), and have to say that I have been well impressed by it. The reason I bought it was to replace my rather bulky Digital 8 camcorder. Image resolution on the TRV33 is excellent and handling is first class. Also DV In and DV OUT was important to me as was AV IN. If I had any complaint it would be that the supplied battery does not last very long at all. However at the price you mentioned the TRV33 must be an option. Having said that all of the cameras you mention get a fairly good write up.
I guess the real answer to your question is,
1. Be clear about what you want your camcorder to do
2. Draw up your shorlist
3. Read independent reviews
4. Buy camera of your choice
5. Enjoy yourself
