what is asic miner tube ? do you have a link ?
bitmaintech is expensive, 0.58 btc for ony 453 GH/S, plus it does not have a PSU
I've noticed this:
http://www.x-hash.com/pro/a1
~~I could get 10 TH/S for a relative low price with immediate delivery. it is 609 per unit per 1 TH/S~~ including PSU.

Aside from the solid advice given here...

You're probably making a huge mistake if you order from Xhash... or from any company that doesn't have an active thread in the Hardware subforum.
Please do your research or you WILL get burned.

What you failed to notice is the extra zero on the end of the price -
" Price: 6090.00USD"

they are charging Six Dollars and nine cent per GH.... WALK AWAY

Bitmain miners are solid and reliable. They ship when they say they will.
SpoondooliesTech if you want to preorder.
or if you are happy with self assembly - AM tubes shipping now-ish. https://bitcointalk.org/index.php?topic=735728.msg8310763#msg8310763.
Also Look at BTCGarden or KNC or Lighteningasic or Bitcrane or or or....
Or maybe even consider MegaBigPower Franchisee
