i have built my own incubators in the past that worked very well and sure you can customize it to your needs but your needs may change like mind did. i went to natures spirit and purchased thier large incubator and have hatched colubrid, leopard gecko, bearded dragon and ball python eggs in it. its a well built quality incubator, alot better than anything i ever made myself and if your not handy its the way togo.
