My bucking saw is a Chinese 365 clone. It is labeled a 'HH365' - the price over the internet was A$230. That is well below the A$1600 that a Husky 365 was priced at. With the 77cc jug and mods - it is an animal. One of my mates had an old open port 365 that I upgraded for him and he loves it. He only runs a 20" bar, so I put an old 8-pin on it that I had - he can't bog it in Ozzie hardwood.
I don't know know the quality of the '365 kit', the quality of the Chinese stuff varies considerably. However, if you are building a cheap saw for a limited use it may do the job.
