Affirmative 1:1 is safer compared to 1:10, but you need to ensure that your firmware supplier is reliable, otherwise you will never know how many people are sharing the same firmware with you.
Directly finding firmware developers to purchase firmware is the safest option. They can create their own firmware, and the only cost for them is the time spent. However, for firmware resellers, they need to pay the firmware developers in order to obtain the firmware. They can then sell the same firmware to multiple users, earning several times or even dozens of times the profit. Of course, not everyone does this, but you need to assess the potential risks.
For regular DMA, you can directly purchase one without firmware. Just make sure it has a low price, good quality, and good after-sales service. Then, find a reliable firmware developer to purchase the firmware. This is the most cost-effective and safest choice.
