I just recently bought a new avant 420, wow what a game changer. As the initial cost was up there I wanted to get just one attachment with it for now so ended up getting a grapple bucket. If you're looking for one do it all attachement this serves us very well. I was going to pick up a bmg but after using this for a couple months I see no need. We did a planting in my front yard using 22 yards of soil and 10 eight foot Norway spruces. I had all the soil moved and all the trees in place in an hour and a half. Its so easy to grab the large root balls. I can grab large logs and brush piles with ease, long ways or sideways with no help from anyone having to position a grapple or the debris. To be fair ive never used a dangle grapple but ive seen lots of videos and did a bunch of research. I wanted one do it all attachment to get us started with the new machine For me at least, I really don't see a need for another attachment.
