I actually also bought Probe 6-8 today too (most recently released EP) - earliest (Electronic Meditation) and most recent releases - I'm into both! Some people complain about the stuff since Edgar Froese died, but I like the most recent stuff much more than the 80s stuff for example...
Yes, the current lineup is kind of a throwback to 70s TD with some of the less cheesy 80s influence thrown in. Froese was never one for standing still and he always embraced the newest trends and tech, plus he started getting the band involved in soundtracks for film in the 80s, all of which resulted in some pretty cheesy stuff, alongside a few gems like Love on a Real Train. There is one album from the late 80s, Optical Race, which can be considered cheesy depending on the mood I'm in, but I still listen to it from time to time because at the time it came out in 88 it sounded futuristic and brings back some good memories of what I was doing in those days.
I saw TD in Philly in 2012 and got to shake Edgar Froese's hand after the show, it was a fairly small club venue and a good time. I'm glad his bandmates decided to keep the project alive after his passing.
