I have a GQF. It is a super old model, but works just as well as a new one. I gave $150 for it and it has worked perfectly from the day I got it. Well, it doesn't work so well when you kick the power cord out!
I also have another GQF that I use for a hatcher. It is a little newer. I gave $150 for it, too, but have had to do some modifications on it. It needed a new wafer thermostat, which is not expensive and I had to make lids for all the hatching trays, which is no big deal, either. My DH recently put a reostat on the fan because the thing blew like a hurricane. Now we can adjust it however much we want. It had way more air flow than it needed.
If you are just wanting to hatch a few eggs, these would be pretty big and take up quite a big of space. I don't know the dimensions, but you can look them up on
ebay or a number of poultry suppliers that sell them. They are expensive to buy new. Once in a while one comes up on craigslist, and that is where I found both of mine. You can still buy parts for all of the old ones.
As far as smaller incubators, I really don't know. I've heard a lot of good things about the
Brinsea, but I know they are expensive for what they are. My recommendation would be no matter what incubator you buy, get a circulated air model with a turner! Oh, how I wish I had a turner in mine. I guess that is a modification I'm just going to have to make one of these days. I know I don't turn my eggs as much as I should.
Hope you find just what you want!
What kind of incubator do you have???? are they pretty easy to operate>>>?? ive been wanting to get one but dont know the best brand, i have been looking at the brinsea 7 egg incubator to start out with, is it worth the 150.00 price tag????
