I got hooked with a solo miner and needed more. Didn't want to deal with international orders than I found Altair. I first purchased the Avalon Q and everything went good and mining away. Still needing more I purchased an S21 XP from Altair. They shipped it directly to my hosting company and its hashing away. I would recommend Altair especially in the US because they did all the international stuff and I got a miner in a couple days. They also have support ready to help
