buying a grapple but not an accumulator?

We are an operation That does about 12k bales a year, 4K of which we do for custom baling. For our custom jobs we just bring our tractor and baler (2013 NH) and they supply the racks we stack right behind the baler. We will hopefully have 10k or so bales of our own this year to handle, so we were thinking about getting a grapple to unload our racks.
My question is have any of you had experience with using a grapple to unload hand stacked racks? We do quite a few small or hilly fields that an accumulator wouldn't really work for, and it's out of our affordability for another couple years anyways. would it be a good idea for us to get a grapple to unload our hand loaded racks? We only have 6 racks that hold 140-170 bales right now, with 2 running gears to be finished up. I figured that if we got a grapple, we wouldn't have to build any more racks, which would save us money, and the grapple could save us a lot of unloading and a need to hire an extra hand or 2 every time we bale.
I was hoping I could get some suggestions on sizes, and brands. I saw some decently priced kuhns grapples that were somewhat close to our operation. A problem that might come up with using a grapple I've noticed is not really made for the typical hand stacked rack, just for an accumulator drop.
any advice or experienced shared would be greatly appreciated.
thanks,
jason
