If you are just hatching in it and don't need an egg turner or turner cradle, you could go with the Brinsea eco. It does require the temperature be set when you first start using it, but mine has held the temp through three hatches without any further adjustments. It hold humidity well and is easy to clean. You can get it for $99 on sale. It looks just like the Brinsea advance but doesn't have the push button temp settings.
now, that being said, its pretty crowded in there when they start hatching.
