Cannibalize an LG for a new incubator, or start from scratch?

[HaikuHeritageFarm]

I got a second hand still-air LG incubator in semi-rough shape and am regretting it. the styrofoam is pretty beat up in spots and I'm blaming that on the variability of the humidity and temps that I'm getting.

So, my question is, should I cannibalize this unit and put the components in a nice new styrofoam box (salmon season in AK, styrofoam boxes for shipping frozen fish are plentiful and cheap) or just build a new one using a light bulb, etc?

I say tear it down and start from scratch. Better safe than sorry. Id hate for you to have problems with it holding the temps because the styrofoam is questionable. Just my 2 cents though. Either way, good luck!!
