I have 4 of Jacobs molds and have never really had any problem with him, but in talking with others I hear a lot of what Andrew is saying.
Like Caney's molds, his shoot fine and without any issues.
Not every mold maker is going to have what you want so you do have to look around and weigh your options. To be sure, Jason and his family here get most of my business but Rick has some designs that I can't get here.
