Combo Stumper and Rake

Hey Guys. Need to know if anyone has any experience using or knowledge of the USA Attachments combination Tree Stumper and Rake? Primarily are there any pros or cons to be aware of? Is it durable enough to do production stumping jobs. Is the Rake heavy enough with being "bolted" on with only 4 bolts? We are looking at putting it on a JD 160LC Excuvator. We need a Stumper primarily and we need a Rake occasionally!! So we saw this and thought, that is exactly what we need....I think!!! It is pricey at $4300.00 new, but then buying separate pieces probably works out about the same. I would greatly appreciate any feedback.
