I had a great experience importing my diesel. There are a number of shady operators in the engine importing business - at least I recall hearing many horror stories from kids trying to buy performance Honda engines etc. through import houses. Best to go with one that is established and has a good reputation - worth the extra money every time. Also, make sure you use a credit card so you can dispute the charges should the worst happen.
