welcome Amabir If it were me I would by the engin and alltinator from sorces close to your home and had a good reputation and in the future if you needed parts or had questions it would not be as hard. I've herd of a few names of the engins and all the people that have them love them, is 1 name better than a different name. I don't know, alot of the parts are interchangeable from 1 name to another name.
Keep us posted on your project
