Hey Jim,
I just got done wrestling with the same decision as you. I really started off looking at the B3300SU, but finally decided on the
L3800. I really like the
B3300, but I was worried about the lift capacity of the loader, especially with the Kubota quick attach, as it pushes the bucket or forks out a few more inches forward. The extra reach is nice with that, but I am not positive the amount of reduced lift capacity. I also did not like the 1/4 inching 3-pt. The
L3800 is over kill for me as well with only 2.25 acres, but a ton of projects to do. The
L3200/ 3800 also has the skid steer style quick attach available which is very nice. I had one in the past and loved it. I looked at a
L3800 and
B3300 side by side at the dealers lot a few days ago and as you said, the size is almost identical. The
B3300 did not have a loader on it. I think if you compare the loaders, the loader on the L's just extends out further which gives you better reach and lift heights. Also, makes the whole set up longer, which may be a negative for you. The same dealer had a used
B3300 with 17 hrs on it that came back and traded in on an
L3800. Here is a link to a thread, if you have not seen it already, that has an
L3800 w/FEL picking up an approx 1,800 lb. bale.

Good luck in your decision,
