Yes there are a few of these Chinese copies around Tyler ,the cheapest I saw was $85. so $52. was very cheap.
I have the NB40 robin motor that was missing parts when I found it so I didn't realize what it was.
I think I only have 2 MSAA Trimmers , both run well and I would have a few of the Echo equivalent trimmers , the only one I could find that was close looking to your MSAA Trimmer Tyler was a Homelight HK 16.
Looking at my 2 MSAA Trimmers they are both CD Ignition.
