Hello,
I have one question to you 
Where can I buy a cheap lucid dream mask ?
Yes I know about Kvasar , Rem Dreamer etc , but I would like the buy cheap lucid dreaming mask like this :
commercial link removed 
60 $ 
Other web pages ?
You could search sites like Ebay for used masks, especially the Novadreamers can be very expensive though. But, you could also build one yourself. If you search this forum, there should be topics about home made devices. I removed your link btw, since commercial links aren’t allowed on this forum.
Yes I was searching on Ebay but there is quite expensive devices ;/
Yes I know that i can built my own dream mask but i am not a electrician ;( 
If anybody have link where can I buy lucid mask (cheap) please send it to me by PM
Much appreciated
Ok
