Hobavators work pretty well. I would strongly recommend
however that you get a backup thermostat and place the probe
in with the eggs. I always double protect all my racks and cages. You don't want to know how many thermostats I've got
on my incubators!
The best case (although a little more expensive) is to get
a proportional thermostat and make sure that is the device
that is gating the heating element. That will keep your
temps VERY constant. The generic hobavator thermostat will
probably keep the temp to within /- 2 degrees. This may
sound like a lot, but it isn't too bad. Put in a min/max
thermometer to monitor. If the 'high' is 91 and the 'low'
is 87, then the 'average' is ~89 degrees, which is just
fine. Again, if you use the proportional thermostat instead,
it should keep a much tighter range.
I have most of my eggs in a larger incubator, but I still do
keep a couple clutches in the hobavators just to spread them
around a little. I don't like to have all my eggs in one
basket (er, I mean incubator!).
Good luck,

PS: 1000g is really on the small size for breeding. It is
possible, but 1500g is much better. The 30 females that I
bred this last season averaged over 2100g!
