The Pulsar Recon X550 (#78026) is certainly WORTH the money. If your goal is to see in the dark with very good to excellent resolution, you want this unit. Its light gathering ability is quite good, but understand this is still not a 3K dollar Gen 3 device. You'll still need to occasionally use either its built in IR light (Max 75-100 yard range), or even better would be to purchase a high performance IR light & mount it to the accessory rail. The "Sum Light" digital signal processing program (which can be turned on or off) ensures very good low light gathering, this is one of the many features exclusive to the X550 model. The "Sum Light" (DSP) simply amplifies the available low light, letting you see farther into dark areas. The X550 also has a video out port, this is quite useful for hooking up either a small to large monitor, or a video recorder. Preferably you want to use a HD recording device to take full advantage of the X550's higher resolution. Last, there's over a 50% increase in pixel count between the X550 & the less expensive 550 & 550R models, making the Pulsar Recon X550 the clear high resolution winner.
