Used Helix Floor for $800? What to look out for? in Helix Posted December 12, 2023 Buying new is the safest bet of course. I bought my Helix floor as a used unit but it was mint, it was from Ebay, and the seller had excellent feedback, so I was confident in that purchase. You have to be patient sometimes to get the right deal if it's a used purchase, and perhaps make an offer on one that is in good condition.
