If you're on a budget... my 1602N (no turner or fan) works really well... with blankets added to the outside. Working the wafer isn't too hard. There are no built in bells and whistles.
My 1588 also is fantastic with a fan and turner. It has temp and humidity display, but should always be backed up by calibrated equipment.. It does seem to hold it's temp more stable than the 1602N which fluctuates slightly with room temp. DON'T waste money buying one that sets only 12... You can always set less eggs in the bigger bators but you can't set more in the small ones. Plus I add water bottle heat sinks... to help hold temp in case of power outage. I thought oh God, who needs to set 40+ eggs?! Turns out... I do.
I now have 3 incubators that ran almost all year non stop.
I use 1 or 2 as hatchers and set new eggs every 4-7 days.
What I won't recommend is the double stack 90+ egg bator for around $75 on Ebay... that gives my cruddiest hatches and requires the most amount of manipulation. If it's a clear plastic box... you know it doesn't have any insulation. I still get hatches from that one... but never as good. It is nice that it has humidity and temp display and it also has a day count down timer... and one whistle I kinda like... an alarm that goes off when the humidity drops too low or temp goes too high.
If funds aren't an issue for you... then I'm sure there are nicer ones.
My hatching chicks have less sticking issue in still air than circulated, but that might be related to my incubation evaporation/shell color. I like the forced air for incubating but prefer still air for hatching. And got my VERY best hatch rates in the still air, hand turning... maybe I was just less sloppy in the beginning (also less experimental). Good luck finding one you like.
