OP here, I found a build sheet I worked from Kubotausa dated August, 2020 before I purchased my LX3310 off a dealer lot.
The list price of the
BH77 was $7051, the 16" bucket was $658, and the thumb was $482, and the subframe was $953
for a total list price of $9144.
Not sure exactly what I actually paid as it was a bundled, (minimally) discounted deal with the tractor, FEL, etc. and eventually included sales tax.
I just went to the KubotaUSA site and configured a LX3310 and the list price of the BH, thumb, 16" bucket and subframe is
$11,651 (up $2507 in ~2 years) with what appears to be limited availability.
