no clue on pricing, but if your only throwing the disk in once in a while, just back in carefully, 12' is lots for an 11' disk, just don't rush. sadly its common to have about that kind of clearance in pro ag. shops (at least the 3-4 I have worked in, stuff is just to big!) so. would recommend to go as high as you can, loaders etc need high, that and the option of running a overhead hoist is a really sweet option if you can swing it.
