I responded to your post on SMF, but will here too just to give my thoughts.
I just ordered my #3 last night as well.
I was in the same boat as you worrying about getting to max temp and you may see several posts on this forum expressing my concern. But the more I read through all the posts and responses to my concerns, they have pretty much been alleviated.
I know there are some having trouble with this. But there are many others that aren't.
I am going to try it sans Auber PID and see how it goes. However, this is easily fixed by buying an Auber PID controller that will give much more precision as well as pretty much take control away from the analog thermostat.
If you want to get temps higher than 250, you can bypass the controller and get temps in the low 300s from what I have read. There are plenty of threads in the Auber Tips & Tricks forum group.
We'll be in this thing together Zebra
I got an email this morning shortly after 10:00AM CST that my order has already been shipped.
Now for the anxious waiting.
