Filling up a 200amp panel with asics for garage warmth

I'm on the hunt for L7s Bitcoin asics and any other models that are actually making a profit. Not looking to pay crazy reseller prices, I've got 50k to spend and I’m cool with waiting to get them straight from the manufacturer. My electricity rate is locked at 0.042 per k/wh for the next two years, so why not put that 200amp panel in my garage to good use? If you have something for sale, drop a message here before reaching out to me. Thanks a lot!

You can check this "Current list of ASIC miner manufacturer/distributor". There are two active manufacturer that sells cheap units the shop.canaan.io and shop.bitmain.com but check the Canaan they are selling cheaper their a1126 pro is around $480. If you are looking for used units try to contact offordscott

Appreciated! canaan is a new one i've been purchasing directly from bitmain for several years now. Since nothing good has come about with GPUs and crypto I figure go back to the ASIC sinkhole.
