So, I was browsing craigslist and this woman has an RL-1 incubator for 50 dollars, I've never seen one before and she sent me a picture of what looks like an older model, she bought it back in 1996. However it still looks as though it's in good condition. I don't see tubs or the extra shelf though, but it could be because it's an older model. Do you guys know anything about this incubator? 50 dollars is really cheap, so I might just buy it anyway.
