Dear friend,
The problem here is that all Antminers are out of stock and Avalon though less powerful and lil expensive are at least available. After ordering, (the site says) they will deliver in 1 week to 10 days. I think, i should order 2 of avalon to startwith and then wait till s9 starts delivering. The bigger order i will place to bitmain. Is it worth the wait ??

I would suggest to start with Antminer S9's, or Antminer L3+'s, I think you should be able to get 2 of whichever you choose for 4k$. As far as I know they are the best bang for the buck on the markets right now.
