Which is better Antminer S3, L1 or Asicminer Tube?

[Lucky7Gaming]

Currently have two S1s, had asicminer cube and blade and looking to upgrade.  What do you guys think is the best?  I realize the L1 is really unknown right now in profitability.

Personally I have electric heat so electricity doesn't matter that much.

Costwise you can get a Asicminer tube for about $400, S3s still go for about $300.....

So, Asicminer is the best choice now if electricity is not a problem

tube is your choice if you can maintain a watch over it.

if you want to ignore it the s-3.  I have a pair in my friends office. batch 1  I set them up in july.

 0 that is correct no maintenance   from july 23rd to sept 28th.  they are underclocked to freq 212.5 and hash at 430gh each.

L1 is a dumb move since you have free power. get a sure thing.
