Searching <100$ laser system for disco

Im searching a laser disco system with:
Lockable patterns.
Ability to adjust the patterns a bit on sound.
I was thinking about this one, or can someone else recommend me something else?
Professional Stars Light Show Special Effects+LED Stage Lighting Projector with Remote Control $89.16 Free Shipping

I got one that does all the same for 28$ on ebay--priceangles may NOT be where you want to go anyway.

this does not do all you are asking to achieve. basically moving star patters-= to the music or strobe efx. no patterns asaik

also known as a Bliss Laser dont pay more than 30$ for one.

Link me...because i have seen cheaper ones, but with less functionality.
