Panasonic Twin Guard Ultra-low Freezers

Any experience with the Panasonic Twin Guard ultra-low freezers?

I have a new ultra-low freezer budgeted for first quarter of 2014, replacing a crappy Revco. Our sendout area has an older Sanyo that has performed well. 

My boss is intrigued by the Panasonic Twin Guards. The prices look pretty good, but I haven't seen any comments on them. Anyone?

If you've purchased an ultra-low within the past year or so, what brand did you get? Are you happy with it?

Thanks!
