I do not have one myself, although from reading the forum, it seems most operators use the Archos. Compared to what you're looking at, it's a lot more cost efficient. This PDR100, does it have a screen so you can watch what is being recorded or for playback? I didn't notice a screen on the link. If not, then that's another reason one would go with the Archos. It seems buying a miniDV camcorder with a video IN is a bit difficult to find. I luckily have an old Sony model that has one, so I'll use that for awhile till I one day get the Archos myself.
Hope this helps.
