You'll probably be saving up for a long time then.

This is my first year and what I have bought:

1 6qt rack (150)
1 28 qt rack (250)
1 41qt rack (300)
Herpstat 2(250)
Incubator(professionally made $700)

I still need to pick up a 15qt rack.

If you can make your own, it'll be cheaper, but you can't skimp out on thermostats.
