Apparently the Sleepyhead software cant always tell the difference either since it sometimes shows my PR 560 auto aflex with aflex set on 2 as a bilevel machine

Personally I went with the PR series 60 auto aflex with heated tube. Insurance would pay the same so cost didnt mattter. I did like swivel for the hose the software upgrade and the PR not being as finicky about the SD card being locked or not when putting it in a pc . Both are great machines.
