Don't go cheap on hardware! Those examples you listed above will not satisfy you. It's always best to spend more initially. Trust me, it's cheaper that way!
A couple of things to remember when looking for a projector:
Scan speed isn't everything. You need to look at the complete specs. That laserworld projector touts 30k but only at 4°! That means that the scanners can probably barely pull 20k ilda. Ilda standard speed is always measured at 8°. If you're wanting to do graphics, 30k @ 4° is going to let you down and make you regret your purchase.
Beware big power advertising. Sure, that Laserworld is 1W but all of that power is in the blue. Also, the red laser is 650nm. For graphics, that is going to give horrible color balance. You'll lose a lot of that power in attenuating the lasers to get a good white balance. I would say the red:blue power should be 1:1 or at the very max, 1:1.5. Also, 650nm reds are garbage IMO. You'll want the red laser to be 637nm~642nm. For red lasers, the higher the wavelength, the lower the apparent brightness. It sounds like it wouldn't matter too much but the difference is striking! 650nm reds look DRAMATICALLY "dimmer" compared to even a 640nm red. Hope this helps!

If you're the smartest person in the room, then you're in the wrong room.
