Videocamera Questions..

So I am in the market to get a videocamera, and I have been looking at Hard drive cameras because I have heard it is easier to edit than miniDV tapes? The thing is I have heard that a lot of Hard drive cameras do not work with iMacs and Final Cut Express 4, which is what I would be using to edit?? SO i have a few different questions I need help with. First, does anybody know of cameras or have experience with editing video from HDD cameras on iMacs???? Which particular hard dvive cameras work with iMac's and FCE4??? Should I be looking at buying a miniDV camera or different source of media??? Also some of the cameras I have been looking at are the Sony DCR-SR45, DCR-42, DCR-SR42 and the last camera is a Samsung SC-HMX10. My main reasoning behind the thought about getting a Hard drive camcorder is that I have heard using the clips is easier opposed to miniDV, I just do not want to get a camcorder where I have to do a lot of work to the files before editing them, Thanks in advance and I am definitely open to suggestions and insight!
