HD stuff is rather cool, but unless you have a fast PC with a large hard disk it becomes very tedious to edit.
Another big decision is what format - SD cards and MiniDV are the two I'd look at. MiniDV tapes are relatively cheap, record for 60min short play or 90min long play, and are a pretty good quality. If your PC has a firewire (iee1394) port you can easily transfer stuff. They work pretty well, and if you want to take a lot of video you can just buy more tapes.
SD cards compress stuff more, so they're marginally more difficult to work with from that respect (depends on software) - but you can skip around your videos, and delete some stuff to make room, rather than having to record over from the start (and possibly go over a clip you wanted to keep). The main reason I went for SD cards is that I often video plays, so being able to record continuously for more than 90min was helpful.
