I am looking for comments either good, bad or indifferent as to the reliability, ease of operation, and power of Magnum 4 strokes. Is the lower cost an indication of quality? 
I fell in love with four-cycle engines after buying my first Saito; a .56. I followed that with a Saito .65 and .91. Then, I bought an O.S. 70. The O.S. runs well, but is very heavy for it's size (heavier than a Saito .91). I preferred the Saitos. After hearing lots of great things about the Magnum four-cycles and liking the price, I bought a Magnum .52 four-cycle. It wouldn't run properly and was returned to Magnum. They replaced it. The replacement would not run right and it was returned. They replaced the upper end under warranty and now it runs OK. I would personally not buy another one.
Good luck with whatever you chose,
