Would love to hear feedback on the Brinsea Octogon 20/40 Advance EX from someone. I've about had it with my Little Giant (which I bought this year, and installed a circulator fan seperately). It is a poor performer for me. I've got five temp probes in it, and I have 5 different readings, lowest is 94.6 degrees and the highest is 99.8. Adjust the knob a millimeter and temp jumps to 98.9 to 102.4 ACK! Also, what about the RCOM King Supra or whatever? Appreciate anyone's feedback on any of these products. The little Giant's going in the trash can. Totally worthless (of course it could always be user error).
