Actually all it needs is a controller to run Lightburn.
The control panel is ‘inside’ so temperature indicators and mA meter (which I don’t see) would be covered up unless the lid is open.
So expect to have to run this with the lid open or none of the indicators will be visible… Suspect that’s why this is on sale.
I didn’t see anything about a manual Z table.?
What part of the country do you live in? What you need for cooling can vary widely. I live in the SW desert area and require a load of ice or a refrigerated chiller.
If it’s a K40 type, they are virtually the same animal. Play all the games you wish, there is little difference. You are back to the around $400 to $600 range.
You have another thread running with the same discussion, they should be merged. Maybe @JohnJohn can assist… and merge them…
