redmax/zenoah/efco/oleo-mac/husqvarna/partner/mcculloch
the redmax range of saws are rebadged komatsu zenoah saws, made in japan, they are solidly built, but generally heavier and slower than their european counterparts (hmm, reminds me of echo somewhat...)
efco/oleo-mac's top handle offering is a rebadged komatsu zenoah saw, same saw as the redmax.
husqvarna group now own the outdoor power equipment wing of komatsu zenoah, and have recently rebadged the smallest of the zenoah tophandle and offered it in the husqvarna, partner, and mcculloch range....
so, to conclude the lecture
the redmax tophandles are o.k... (i know a few people who have had one as a 'backup' saw and to train the new kid on before you hand them a 200t/338xpt)... but as a plus parts availability should never be a problem as the same saws are available from zenoah, redmax, efco, oleo-mac, husky, partner, mcculloch and possibly others... pick a color, any color
