The manufacturer of Antminer S3 is Bitmaintech and they are the most trusted company as of now.
They usually deliver from stock or do a short pre-order of less than one month.
Antminer S3 is the latest one and currently Batch 3 is going on. Its the most energy efficient one as of now which is ready to deliver.
Guarantee is normally 3 months but, guarantee doesn't match much in the mining hardware arena.

If you are asking about profitability guarantee that's another topic.
