from personal experiances, i've found most people that have used photoshop or anything lke that prefere GoLive when they start out...when i started i found it much easier to use that Dreamweaver, then again, i was comming from BBEdit 9and text edit before that)....i still find GoLive better for layout grids...
dreamweaver is nice, but i've found it to be alot less stable, and more inacurate with "mozilla" only coding...
you really do want to know at least some html, cause then you can throw in BBedit, change a couple of things, and you're done...otherwise there's lots of clicking and stuff....
basically, you'll learn whichever you get! it's that simple...so, which ever is cheaper and what company do you like more? then go with that...
i use dreamweaver as a last ditch now, only cause i get it for free, othwise i'd use GoLive...of cource, i still do everything in BBEdit essentially...everyone in a while a layout grid gets a little too complex...
and that sports car vs. pickup anology works really well...
oh, and dreamweaver works for the novice, it just has a steeeeeeep learning curve...
