Well, IMVHO there is nothing difficult nor crippled about the exporter that Snarlygribbly wrote. It works just fine for my purposes, I can write my own shaders for it and it's free ;). Sure it's not flashy or particulary pretty and doesn't look as nice as Reality's interface for the DS exporter, but it gets the job done ;). Snarly's been very generous with his time and his scripts :).
