Which brinsea's do you have? I have the mini II advance. I was kind of thinking of getting the Maxi. or another bigger one.
I wanted to get the Maxi as well but I went ahead and jumped on the Mini advance since I was able to get it for less than $100 including shipping and even the scratch & dent mini advance was $169+shipping. If I love it I'll start keeping and eye out for a deal on the Maxi advance and that very well may complete my collection of incubators, lol.
After I hatch the goslings next month I'm going to get myself together to do a thorough side by side incubator comparison test. I'll probably still include the hovabator too since it gets recommended often and it has an upright turner opposed to the others all being horizontal.
