I can certainly understand the frustration with obtaining anything large from the states when you don't actually live there. The cabinet is a fairly recent purchase, and honestly it only became possible once me and the family moved to California in the last few months. Before that, we were living in Japan for the last 10 years.
While I do miss Japan (loved living there and hope to go back), I certainly don't miss some of the ridiculous prices I had to pay for shipping certain things. Attempting to ship something this size was basically out of the question, and I honestly don't want to even guess what it would have costed me. Damn thing probably wouldn't have even fit in our tiny box of a house.
I do miss my ridiculously fast and low cost internet from Japan though. Internet in the states is so bad is not even funny. I paid approximately ~$40 a month for 100Mbs speeds 10 years ago in Japan. 10 years ago....seems like the internet here (USA) has barely gotten better after all that time (sorry for going a bit off topic...but damn the internet sucks here ).
I miss Japan as well. Luckily when I lived there my dad worked for a company that did government contracts and he was able to get super cheap shipping. I remember it only costing like $50 to ship my 30 inch monitor to Japan 2nd day air from California.
That netshelter is quite a bit cheaper than the ucoustic and other alternatives. I currently have a 'server room' that my rack is dedicated to and even my own main machine is in there with some 60+ foot cables but I am actually currently looking at buying a new house and it would end up in my master bedroom's walk-in closet and in that case I need something quieter...
I have been scoping out craigslist and found a few times where ucoustic racks went for $1000-1500 on there (they are $7000+ new).
I could pretty easily afford just buying the net-shelter its just too hard for me to justify the expense when that same money could buy almost another 200TB of disk space instead.
