Choosing an incubator

[BeeKeyPlayer]

For various reasons I'm fed up with my warming cabinet as an incubator. I was thinking of an upgrade and spotted this, below. I'm unlikely to have more than 20 cells at a time but this seems to be a good option without too much overkill. Because the final payment for my holiday is due next week, £199 doesn't seem a huge sum to pay for something I'll always have.

Any suggestions for how I might better spend my money? My experience with using my warming cabinet is that humidity does matter, though I don't know what to make of David Evans's comment yesterday that he sets his home-made incubator to 90%! I aim for 55%. Maybe humidity doesn't matter after all and any issue I've had is caused by something else.

I actually did a search before posting the above. But I've now found this which is pretty thorough!

The Rcom 70 is very good and the customer service is second to none at the Incubator shop.

My rcom 70 has been brilliant this season , I probably could of spent my money buying a normal egg incubator.
Temp is set 34.5 and 50% humidity.
