I also have a Turn-X 7
http://www.lyonusa.com/MARSHCART/910-067A.htm which is with the automatic turner which to me is a must and turning the eggs once every hour does not seem to matter. I have Pionus & Amazon. You really want an incubator that turns eggs automatically. As for brooders, I use Avitech's Brooder Tops and do fine with those and I have 5 of them
http://www.avitec.com/Aquarium-Brooder-Tops-p/avq.htm and use them until babies out grow them, then they are old enough by then to go into larger plastic tubs and won't usually require heat by that time seeing that it is usually summer time when I have babies.
Honestly, when it comes to chick's lives, you do not want to skimp on quality... their lives depend upon that incubator being in good operation 24/7 while they are in there as an egg.
Also in addition to candling eggs, I have the "Buddy" a Digital Egg Monitor where you can see a heart rate and this tells you if the egg is fertile... another expensive thing to have but then again we have all been in position such as "Is this egg alive or not" scenario... don't want to toss out any eggs that may have hatched... this little goodie you will find on this link...
