I have a Janoel 12 and Janoel 24, both from Amazon (think the small one was marketed under the name Magicfly). Happy with both. I've hatched chickens and ducks with good success. The instructions are hard to understand (really bad English) but there are videos on YouTube to help you along. Both incubators have a lot of positive reviews on BYC and were fairly inexpensive.
2x joduh Hubby got me a Janoel 12 for Valentines Day, I had researched it and the Incuview, both had my interest. I have yet to hatch anything, have tested it and temp holds well, learned the ambient humidity affects the internal humidity. The eggs I wanted to hatch became unavailable plus reading about shipped eggs has discouraged me alot. Both incubators have great reviews; Janoel 12 instructions need alot of improvement and Incuview has GREAT CS.
