I bought my Boomer 30 a year and a half ago. For what I bought it for--working wildlife food plots, it's been pretty good. I got it with loader, one rear remote, telescoping stabilizers, and extending 3 pt arms for around $20k.
It does do good with the box blade. With the 3000lb (plus loader) and 4 wd it's able to move dirt and gravel.
After using it, I found the loader is weaker than I had hoped. And now that I have more than doubled my land and I am now in the market for a brush hog, I think the 22 pto hp is going to be a lot less than I would like.
I didn't get the 40/50 because it wouldn't fit in my garage and I didn't want it outside without a cab. I didn't know the 35 existed.
I didn't look at LS because, well I couldn't find a dealer in my state.
Knowing what I know now, If I bought the boomer again I would get the boomer 35 not the 30 for the 38 engine hp instead of 28.
I don't regret my decision at the time, and I'm definitely glad I went two sizes bigger than I originally started looking at, but I needed to go at least one more. I guess I'll just have to pick up a bigger one eventually.
