New models are out at ATA show. May start to see used crossbows go up for sale as guys get the itch for something new.
FWIW, I prefer the Excaliburs. Simple, effective, and easy to do your own maintenance. Their warranty and service department is second to none. I prefer the wider limb models as I find they balance better. The wider limbs and longer power stroke of the Matrix models are kinder on limbs with less vibration and noise.
