An as-is machine is sold in its current state — lowest price, highest risk, and it's on you to inspect, move and recommission. A refurbished or rebuilt machine has been inspected, repaired and often re-warrantied by a dealer, costing more but reducing surprises. Between them sits 'reconditioned,' which varies widely — always ask exactly what was done.
Match the risk to your ability to evaluate and fix a machine. Either way, anchor the price to real value — check the model, hours and condition at The Machine Blue Book before you commit.
