If I can make this, just about anybody can. I am like you and did not like the RF that are out there. I just cast mine so when I break it, I just cast a new one. $10 for a SX-70 lens, WOW! Mine cost me $30 each! Great find. Also, this is my 3rd try at making a RF. So, if it takes a few times, do not worry about it.
