Most cost effective setup?

[I-KandyReptiles]

Ok so I have done more research on BP breeding and the different types of setups than I would have ever imagined was possible. That being said, please don't tell me to go do research. I have done plenty. I've contemplated the AP economy racks, I've thought about DIY racks, and even tubs without racks. I just want to know what would be the cheapest route to go with racks for hatchlings, sub-adults, and adults. I also need the cheapest way to make/buy an incubator (yet I plan on using it for 6-8 clutches so it can't be one of those styrophome (sp) coolers).
So this is what I'm looking for:

1 Adult rack that can hold 5-7 adults
1 Hatchling rack that can hold 20-30 hatchlings
1 juvenile rack that can hold 5-8 for my hold backs
1 incubator that can hold 6-8 clutches.

Maybe the cheapest way to do this is to buy someone's entire collection who's getting out of the hobby. I don't know..

Thanks in advance,
SC

Id go with AP if you're in the states. But if you could build your own racks that would probably be the cheapest.

Look around. I just scored 2 racks for 20% off from a place near me. They're offering a sale for the WCRE show.
