Well, even if you're looking for a "dual purpose" light, I suppose you would be better off with the stuff you originally suggested. It would work, but as I said, probably not the most ideal. I certainly agree with trying to get the most bang for your buck as well. It is something I usually concern myself with. In my case, my market suggested I should get a couple of movers just to stay a few steps ahead. I also WAS getting a few dozen calls a year asking for spotlights(follow spots), but then now I got a pair, the calls stopped. Go figure. At least they have been used twice this season, so I am pleased. Wish my operators would have done their job at event 1. Event 2 was more passive.
Not to suggest an alternate brand, but for less money, I got a pair of Chauvet QSpot 150's, which has a color wheel, a gobo wheel, and all gobos can rotate, and as a moving head fixture, it's less expensive than the ADJ model, and honestly, is the same unit with Chauvet doing it's own branding. But, as Jingles said, no dimming. It uses the shutter to dim, and since it's not one of those shutters that squeeze in, it's more like a paddle blocking the opening, so think eclipse. For me, this is a non-issue, but now that I think about it, might be a feature I demand going forward. Most lights I know of keep that bulb on the whole time, which is wasteful and shortens the usable life of the bulb. Then again, so does dimming. They get you one way or another!
I don't DJ, I have to think overall production as I am a live sound production company, so lights are necessary evil for me to deal with. By getting a moving head with a color wheel and gobos that can move, you do get a lot of other usage out of it.
Won't comment on controllers as my DMX Operator works just fine for my applications. But, if I had the choice and funding for a joystick back in 2002, I would have gone for it IF I knew now where things went for me.
