I did a little Web surfing this morning but am having trouble finding a high-gain (>1.5) gray screen that's still on the market. I had been thinking of getting an Optoma/Panoview Graywolf II (1.8 gain), but every place that had the 120" is sold out; it appears to be discontinued. Can anyone suggest alternatives? I remember the Graywolf getting mixed reviews - some people hated the 'sparkly' effect of the retro-reflective material. I'm looking for something in the 115-120" range, 16:9 aspect ratio, either a manual pull-down or a fixed-frame wall-mount. The Stewart Firehawk would be perfect, but it's too expensive ($2,500). I'm trying to come in under $800.
