This is one of those "it all depends" answers, new and getting a great deal then "yes". Getting one used, inspect it for arc's in the air caps. I never had one but something similar and most reasons they are sold used is arcing.

Look between the cap blades for burnt spots. Most times it is because of over wattage.

I talked to a op yesterday that has one, runs his ALS 600 (500w+/-) to it with no problems, I think once you get over that wattage things start to arc.

Its a roller inductor. The little wheel that follows the winding if it has dirty spots on it they will arc on the wire. I have the same one used and they show some crusty spots. Look at carefully at it. If its burned it wont work right in that range.
