Ok, I'll make some suggestions, keep in mind that they are my taste so maybe better presliten...
If you like Green House Effect - Global Warming and if you are into very melodic psy then try this album:
Yahel - Waves Of Sound
If you like Misted Muppets, even when this style is crazier (and better imho) then try:
Nystagmus - Immaculate Perception
and less crazy
Talpa - Art Of Being None
then some old-school that should still be available:
Doof - Let's Turn On
If you are into housy progressive then I can recommend
Flowjob - Support Normality
and a bit less soft but still progressive
v/A - Street Art
Another progressive album (not housy but very melodic) I really love, and I'm not that much into progressive, is
Reefer Decree - Point Of You
Since you allready have the second Synsun album I can recommend the first one. I like it better than the second.
Synsun - Symphonic Adventures
IF you like full-on then I just have to tell you about my favourite full-on album ever:
Space Cat - Mechanical Dream
and since we are at it check also the first two Space Cat albums out
Space Cat - Beam Me Up
is more old-schoolisch and not full-on.
Hope you will like some of my recommendations!
Edit: Reefer Decree's album name corrected, thanks NextWorld!!
