MIG Switch is way too expensive in my opinion. I believe that some people here think so as well. It doesn't have any official place to buy it from which makes the AliExpress scalpers probably the only way to get them. Maybe a Facebook marketplace here and there as well. Unless things have changed recently and I haven't seen it? I've checked their "official" distributors back in March or April, but none of them offered a reasonable shipping and ETA for me. I'm not going to pay that much money and wait months to actually get or get scammed for doing so in the meantime. Those shops come and go, which makes them pretty unreliable.
UnlockSwitch offers (or promises?) the same (or even more?) for half the price of MIG Switch which is much more reasonable to me and is what I'm willing to pay for. Again, as long as they actually make everything work as it should, which is hopefully something they plan to do after all this time.
I was hyped to get MIG Switch on launch but it was way too difficult to actually get it shipped to my place. If its price didn't kill it for me, the shipping costs surely did.
If it doesn't turn out to be a good deal, I can always decide not to buy it and spend my money elsewhere, nothing wrong with that. Maybe even a used MIG Switch flashcart will drop somewhere for a decent price and I'll buy it. You never know...
