Wife decided on the
Samsung rather than the LG because it's slightly larger capacity. (it's also 3" wider, which I don't like but it's not a problem) I think it has an old-fashioned compressor. It does have a 5 year warranty on the sealed unit and 7 on the compressor. I almost never get extended warranties, but I did on this (3 years.)
I think Best Buy had the Energy Star tags swapped between the Samsung and the LG display models (they were right next to each other) because the Samsung said $50 per year and the LG with the linear compressor said $74. I thought that was peculiar and I looked at the tags, and they didn't identify what model they were for. Online the Samsung tag says $74.
I ordered one of these PEX hoses today from Amazon because I can't find anything I like locally
https://www.amazon.com/gp/product/B004CR4OBS I haven't measured the run, but just eyeballing it, it's about 12 to 15 feet and will have to pass thru a floor. I was afraid copper would kink or something even if I put a loop behind the fridge, and cheap poly tubing would spring a leak for no reason inside the floor joist space.
That hose has captive compression nuts on the end. I may ruin it and have to use copper after-all, but I'm planning to cut 8 feet or so off one end (measure first, and leave plenty of slack) to get it closer to the right length, and so I can feed it thru a 5/16" hole. Then connect it to a real angle-stop valve in the basement, not a saddle valve. I assume I can use a standard 1/4" plastic compression ferrule and brass nut, and with PEX it shouldn't need the little 1/8" metal insert for the end.
