I do see a lot of threads on these two systems, but not much discussion of side by side comparison for the two basic systems ($300 for M&B, $350 for Robobrew). A major drawback to these systems appears to be the discrepancy between the set temp and observed temp in grain bed. As well as the ability of these systems to maintain temp vs. overshooting etc. For example I seem to be reading a lot more about the M&B overshooting the set temp than the Robobrew. Is there any consensus on these issues, which of these systems performs better? Thanks!
