Well, the pro-grade are 7x or 8x that but you need a truck for them and then some putting together, of course. They are not portable.
This one is limited to 3.5 cm thick branches. There were 30% or so cheaper options but they were limited to about 2.5 cm thick branches and their openings were not designed as well.
This one should do. 2 KWph, and it says it can process up to 80 kilos of branch stuff per hour. Of course, a lot depends on how good you are at feeding it manually.
