Bought a ACA 1231/42, just have to wait for it's arrival. Appears to be the best value.
Not sure why Amigakit isn't selling them so went through Vesalia. Looked at the ACA 1232, more RAM but slower.
Interesting to see some actual benchmarks being posted. Took some digging to find information about the ACA 1230.
I noticed with the ACA 1230 it has a removable CPU (without soldering), that could be interesting ;-)
