New or used Antminer S19 Pro: what's the better choice?

I'm looking to grab some S19 Pro 110TH/s, thinking of getting up to 10 of them. Not sure if I should go for new or used ones. The new ones are pretty pricey (like $15K-$16K right now) but I figure I'd recoup my investment before they start having issues. On the flip side, used ones would save me a few grand per unit, but I'm concerned about whether I can make my money back before they fail. Most of the S19 Pros are under a year old, and I could fix them if they do break down, so maybe that's the smarter move? Looking for some advice. Appreciate it!

If you use it yourself, suggest you buy a second-hand S19 pro 110t. Second-hand machines are cheaper than brand new ones. The quality of S19 pro 110t is very good, and there are few opportunities for maintenance. There are many second-hand machines in China that are still under warranty. You can choose this one. I have bought an L3 + from https://www.miners-bitcoin.com/, and the quality is also good

Be careful on buying a miner on unauthorized reseller or non-verified distributor you will end up receiving problematic units with no warranty support. Just like what Bitmain said they don't support if you buy miners from non-authorized/distributors. You can buy a used miner but always find the trusted one that can help you troubleshoot in case of any issue related to the miner you buy. If you are looking for cheap units I suggest you contact offordscott or check one of his post from this link below - https://bitcointalk.org/index.php?topic=5187550.msg58896176#msg58896176
