I hear those okr chips are good and reliable. For about sixty bucks I'm going to guess that's the cost of parts and you built it yourself. I've been considering trying to build one. Been watching videos on how to solder as I have absolutely no experience whatsoever. Also been looking at wiring diagrams, schematics, etc. from mamu builds and others. It's like another language to me. Lol. If I do decide to try then the first one will cost me a bit more as I'll need soldering iron, clipping stand thing, tools, and whatnot. I'm interested in building the okr 10 and the other one that company came out with which I think is called the okl2 t20. Also the raptor chip which is hard to come by at the moment.
I for the life of me have a hard time soldering as well lol, your not supposed to touch the iron to the solder to melt it but i can't seem to get what i want to solder hot enough with the iron , what a nightmare that is .
Circuit board soldering, i heard is even more touchy , you can ruin them with too much heat.
