That's more up to how much you want to spend which is up to you.
If cost wasn't an issue I'd get a
Brinsea Octo or something along that line but for me cost was a factor.
If cost is an issue and you are handy you can build a homemade incubator, results vary based on your skill and understanding of what is needed to hatch multiple thread laying around for that one.
If cost is an issue and you aren't handy you can buy a Little Giant with egg turner and fan for about $100 (of course I'm about to buy 3 off of craigslist for the same $100) be very careful chickens and hatching are addictive those three will bring me up to 5 little Giants. Cause later you'll want your incubator to be seperate from your hatcher LOL. that was you can stagger incubation and hatches. The little giant takes some very specific conditions such as a stable room with out drafts. I have hatched several batches with 50% hatch rate or higher on shipped eggs and with power loss. I am now on my 3rd hatch but I lost temp due to unstable room temp. The cold dipped in an my heater in the house wasn't on so we'll see how this hatch goes.
If cost is an issue but you really only want to hatch 4-5 hens then the
brinsea mini is only like $69 but then you have to hand turn eggs. it will hold up to 10 eggs but 1/2 will be boys so that would be 4-5 hens.
There are other brands and they all have advantages and disadvantages. Until you hit the big cabinet incubators the
brinsea is kinda considered the best if you spring for the more expensive models especially the model with automatic humidity control it is really set it and forget it.
The LG (little giant) is the cheapest for number of eggs and has it's own thread for Little giant tricks. I'd read up before putting out the money. I like my little giants and have been mostly pleased with the results but if I wasn't a cheap skate then I'd have a nice big automatic
Brinsea with the Ova scope
