The CID grapple is a ~$3k piece, weighs 200# more (eating into the carrying capacity and wear on the front axle / need for counterweight), is probably mild steel; versus the LP grapple which is ~$4.5k and made from AR400 steel. The LP is much nicer. Consider the LP unit to be at least a $1.5k price difference - I'd personally consider it worth more than that in the price difference because of the noted differences (earlier this year I made a similar choice in grapples between mild steel & heavy & cheap vs good steel & light & a bit more $; guess what I chose).
Is the local dealer also adding the 3rd function? If not, that's an added expense as well.
Do you anticipate actually having a "relationship" with the dealer?
I've had a long term barely-there relationship with my tractor's dealer who's 100mi away - I bought it 8 years ago, shook hands, they delivered it a few days later, we shook hands again. I've bought sundry parts from them via phone call -> mail delivery as well, nothing to fix problems with the tractor (except a radiator which was very much my fault). If I'd bought local for a "relationship", I would've paid a ton more for much less tractor, which also may or may not have needed a "relationship".
