you should have no problems with the riya dac, but if you want something a little more advanced, pick up an etherdream dac.

do not be concerned about the output quality of a riya/etherdream dac and an fb3. one of the big advantages of the etherdream dac is it connects via ethernet and speaks tcp/ip. i would choose a network connected dac over a usb connected one any day of the week.
one issue with quickshow and beyond is they won't export frames/animations/shows as ILDA (the laser industry standard format). if you stay within the pangolin ecosystem this is not likely to be an issue, but if you're interested in playing shows off of SD cards or sharing them between software packages, you're out of luck.
i have lasercam and will be featuring it very heavily in some of the next shows i create. in the meantime, here's a link to some of my experiments with it. in a nutshell, it's excellent and can be a very powerful tool.

I have even researched and evaluated all software available in an entire industry in short periods of time to be able to improve and innovate new software designs. Learning DMX hardware lighting controller programming and midi programming... that is something I have just struggled to grasp (Chauvet Obey boards specifically, maybe they just don't do what I thought they did physically)... It took me a bit to figure midi mapping out (I have successfully programmed my Roland vDrums via a USB Midi interface mapped to a professional level electronic drum/percussion software and Logic Pro). I'm pretty confident I could master any of these laser software applications, including LaserBoy on Linux or Mac. I really want Beyond not QuickShow and the price of Beyond more than scares me away right now and the features listed for LSX seem pretty desirable both on the hardware and software side. I'm just not sure if that Riya interface, which can also drive animations off SD cards and has Ethernet connectivity performs as well as the FB3. There is something to be said about industry 'standards' such as Adobe PDF, Microsoft Office... If FB3/Pangolin is that industry standard, it may be worthwhile having/knowing just for interactions with everyone else in the industry.
Overall, I'd prefer a more advanced software that I could grow into. Right away, I just want to be able to set certain drawings constant (auto/sound active modes don't give me time to set a scene and adjust manual camera settings). I'd just start with tunnel circles and some abstracts for photography purposes. Then I'd start making my own drawings (don't want to be limited to just bitmap/gifs and may want to model with 3DS). That LaserCam app it comes with looks interesting as well. Has anyone tried that? I was considering building my own hack-a-dac interface to use with Laserboy, so I think either of these would be more than I need. I'm just worried I'd be all tied down to pangolin's proprietary software/drivers and feel like I may be able to get more inventive use out of the Riya/LSX/LaserCam package. If I had a spare $1200, I'd rather purchase an analog RGB projector than buy software I hope to replace with my own software some day. I'd rather put the money into the hardware. Has anyone used the Riya multibus?
suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.
