The most important things to understand about mpeg:
1. It compresses temporally as well as spatially, meaning that it
reconstructs following frames based on changes from preceeding frames. This
makes it extremely difficult to edit, unless you're doing only simple cuts
edits.
2. Mpeg, like other compression schemes, is "lossy," meaning what comes out
isn't as detailed as what goes in. Mpeg compression, at high bit rates, can
be very effective. However, at DVD-compliant bit-rates, it will produce a
noticeably degraded image than you would get from miniDV, which does not use
mpeg compression.
3. Because mpeg uses temporal compression, it is most efficient when it can
analyze what is coming in compared to what came before. To do this requires
more than a single compression pass. Computer software that transcodes
video to mpeg can do multiple-pass compression. On-the-fly hardware
compressors, such as found in DVD and hard-drive consumer camcorders, do
only single-pass compression. This results in further degradation of video
quality.

It will be easy to transfer, but so is miniDV -- the transfer process is
exactly the same. It will take up less space because it is more highly
compressed (and, therefore, of lower quality). It will be far harder to
edit.

You have to define "fancy." Transitions, color correction, effects and
titles will be very difficult to do, and you'll have an extremely limited
set of fairly crude editing tools to do it with (unless you want to spend
more on your software than the cost of the camera).

The goal is not to use an on-camera light, which results in harsh, flat and
uneven lighting.

You need the eyepiece for bright light, not low light -- bright sun can wash
out the LCD screen.

If you have $1,000 to spend, I'd think this is a very poor camera choice.
You might look at some of the higher end Sony and Canon 1-ccd miniDV
machines, as well as Panasonic's mid-range 3-ccd machine.
