Alternative Barcode Scannerss

I’m looking to pick up some barcode scanners to use with iPads.

The documentation shows compatibility with:

Socket CHS 7Ci
Socket CHS 7Xi

The 7Xi is $440, vs the 7Ci at $211.

What’s the advantage of the 7Xi? More rugged?

Also, it seems both scanners are imager based, vs laser based. I’ve used both technologies in the past on desktop POS, and imager based scanners are slow and awful. Are they still slow and awful?

What about compatibility with the 7Mi or 7Pi, which seems to be the laser based versions of the 7Ci? Anyone used those models?
