I would not have a problem with any Everlast machine with Mosfets mainly because I know the warranty is good. On the other hand I would never buy one that has to shipped back to China for repair.

All brands are going to have warranty work, the last Syncrowave 250 I bought got out of the factory with the 14 pin Amphenol plug not soldered up and the new Smith flowmeter would blow it's safety disc. It all got worked out under warranty and I am still a happy customer.
