Thanks Gil. I will probably stick with OKMO.

I don't have experience with the HM 01 however I have heard less than stellar comments from some owners.

I like the look and size of the HM-01 and wonder how it compares to Jin’s engines. I would like to hear the thoughts of anyone who has both to compare.From everything that I have seen you can’t go wrong with an engine from OKMO.
