I have a Heathrow Scientific Mini Vortex that I got from Amazon about a year and a half ago and paid around $70.00 for it. It does a great job and seemed to be somewhere in the middle price wise. I use mine primarily for dropper bottles like Vallejo, Reaper, Scale 75, etc. but there hasn’t been any hobby paint I haven’t been able to mix with it, including the larger craft type paint bottles.
