Thanks for the compliments!
I do have a laser, a
Beamz Juno 4. It's cheap to buy, but the build and output quality give that away quite easily. I wouldn't reccomend it really.
This is a testrun of the laser in my living room:

As you can see, 'Full four colored laser' is quite an overstatement
Normally the laser is only used to accent some parts of trance/dance songs. It mostly doesn't get used longer than a total of 5 minutes per 5-hour party. However, the laser looks quite nice on video, so a lot of 'lasered' material ended up in the resulting video
Blacking out some of the other fixtures to accent the laser a bit more is a great suggestion. I already have override buttons to blackout my washes and/or my MHs, I'm gonna use them next time while the laser is switched on. Thanks!
