This is such an often repeated query I might make an FAQ of it
Redsox_Mark has not long ago done a very comprehensive Pro/con post of the formats which he might be able to find
I suggest you get a cup of your favourite brew and have a look at the threads below before someone come along unless you then have a specific query
The first would be: What about your current MiniDV did you not like? How much editing will you be doing?
Although MiniDV footage becomes Mpeg for DVD It is much higher quality before that and by choosing your software and encoding properly you get more control over how it turns out
Also you do pay more for the "newer " HDD" technology so pound for pound The MiniDV is Still better VFM as long as you are not comparing a very good HDD model with a mediocre miniDV one;
MiniDV tape vs HDD is not VHS vs DVD

although it seems the manufacturers are making less tape models for SD this is probably driven by demand and not a indictment of tape. For high Def HDV (tape) and HDD models are still being released side by side although Panasonic seems to be embracing Flash media over tape
Tape still remains the Semi Pro / Pro choice , ...for now
Im not so much as asking you to get tape but to remind you that it isnt dead yet .. If you did want to go for HDD get a model whose IQ would not be disappointing.. DVD camcorders are( I think ) really just about convenience .. just pop it into the player after recording ....
