I have 3 Incubators left, that when new were between $4500 and $6500. They are not your avg. incubators. These will incubate from below freezing to 120 degrees and a couple of them also have lights for light cycles depending on what you are incubating. These are from a labratory that closed down. They used them for fish cultures that needed light cycles. You can use them without the lights as well. These things are top of the line. I'm asking only $500 for each incubator. These are huge. Little mini fridge sized incubators sell for over $1000. Buy one of these for way less and have about 6 times the space of a mini fridge incubator.
