They only want $800 for a 3rd function?? Installed??!!!!?
I'd be on that like a duck on a June Bug.
I paid almost $900 for my WR Long 3rd Function and about lost my mind putting it on. I can only imagine what it would be like with a Cab.
When, not if, you get a grapple, you'll understand.
Even if you don't, you may need it for something else and if you do, you REALLY don't want to be putting it on yourself. Do it. I wish I had.
The longer you have that thing, the more things you'll discover it will do. Do it now or do it later. It's only money.
And your sanity.
But I was in a hurry because when I bought mine, (JUL '21) there just weren't any tractors -- Anywhere. There were big boys available, 50+ HP. But even they ran out after a short while. So I had to take what I could get and the Dealers weren't in the mood to negotiate. At all.
Do it and don't look back.
