Has anyone ever seen an American Dj Opti-Par? I doubt the company American Dj actually manufactures it, because I have seen several "clones" on the market with different names on them. Anyways, they are 'similar' to an ETC Source Four Par, at least the aesthetics are, come with a complete lens kit (NSP, MSP, MFL, WFL), rated for 575 watts (HX-600, GLA, ETC...), and can be picked up for about $85.00. They seem sturdy enough with their die-cast housing, they are cheaper than an Altman Professional Par 64, they consume less power, come with lenses, have lamp compatability with many ellipsoidals, and are available in black, white, and chrome. I've seen this on www.stagelights.com and elsewhere. I'm just wondering why the big, power-hungry par 64's are still more popular when they are seemingly more expensive to operate.
