Believe me Randy - I hemmed/hawed/hummed and procrastinated for three years before spending the money. So far I've had it four years - not a moments problems - I've yet to take if off for the first time. Its even a lot more universally useful than my bucket.
Costs - in all likelihood any 3rd function you get will be about the same cost as mine. I would strongly recommend the WR Long unit and if you order a grapple from the dealer also - you likely can work out a package deal on purchase & instal. Its also very likely that whatever grapple you choose will cost less than mine. Land Pride has reduced the cost of theirs and you most likely do not need as heavy duty a unit as I got. Newer designs are allowing grapples to be lighter and stronger.
There is a implement manufacturer about 70 miles north of me - ANBO, Colville, WA - that makes excellent grapples. I considered getting an ANBO but the dealer gave me a good package price on the one I have.
If you decide you need/want a VERY SPECIFIC type/design grapple - ANBO is the place to go. They can/will modify any of their grapples in most any fashion you need/want - within the limits of good sound engineering. I've visited them several times - I've seen a couple grapples they made - one weighed 8900# - big enough to grab and lift the entire left side of the earth. It must have been a monster of a loader that was capable of handling a 8900# grapple. The steel on this grapple was 1 1/2" thick. It would surely test the limits of the steel weight blocks on the back of any loader.
