Especially the Apex 570, looking for the good and the bad. Would you buy another? I seem to remember a fair amount of no heat/overheat issues, and bimba(?) Valves, has any of this been addressed or eliminated on the newest models?
I have one. SS570. Love it. As with any machine, you need to study how it works, then troubleshooting is not a issue. The manual that comes with it is very in depth. Read it and become one with it.
