My thoughts? If you're just buying it to look at, just buy what ever you want.

Get one as pretty or basic, functional or useless as you want.
What I found quickly: http://budk.com/catalog/product.jsp?productId=159690& Much cheaper than the one you linked.
Heh, I have on of those. Pretty nice, but I prefer cotton or leather wrappings to nylon just for reasons of comfort.

Damascus steel isn't a real thing anymore. Anything you see labeled damascus steel is regular steel stained to look like damascus steel. The actual method for making real damascus steel is lost to the ages.
If it's only as a wall hanger, I wouldn't spend $180. If it's for semi-functional cutting like messing around with plants (green stems only, don't cut branches!) I wouldn't spend more than $100. If it's for cutting tatami mats, either for sport or hobby, look for one with differential hardening. It makes the edge harder, so it's more durable and potentially sharper. It also helps prevent the blade from warping or shattering. If you really want to spend money, find one with a folded edge.
I have a $100 "functional" piece of junk that fell apart after a couple weeks, and I have a $60 functional beauty of a blade (which isn't sold anymore IIRC) that's survived well. Neither are differentially hardened, but both have a brushed on hamon (the wavy discoloration differential hardening creates). If you want something pretty, brushed or acidic hamon are alright, but it's not real differential hardening so don't be fooled.
http://www.sword-buyers-guide.com/ is a fantastic site by the way.
There is pattern welded steel, which is a modern attempt to recreate damascus steel, but there are still a lot of fake damascus (etched metal).
Well I am more of a Katana Denthusiast as I feel like they are the most romanticized weapon in our societies. Despite them not really deserving the fame they get. Good weapons, but nowhere near the point that most people think of them as the ultimate sword or whatever.
About the sword? See whothe maker is and research that person.
Even as a katana lover (I have five of varying qualities) but I have to say QFT.
