Been on kind of the same road ourselves except that we already had a 1034 bale wagon we bought new back in the '70s which needed some work to be functional.  Personally I'd rather have a Kuhn accumulator since our hay fields are spread out some but since we already have the bale wagon I think it will work okay. I plan on buying or building a grapple that will handle a 15 bale stack from our bale wagon so on fields further from home the bale wagon could stack at the edge of the field and we could transfer the bales to other wagons so they can at least be moved home and backed inside the day they are baled and then stacked in the shed the next morning while we are waiting for the dew to burn off. 

The reliability of the bale wagon does concern me a little but if we could pick up a second 1034 for $5,000 or less we'd still have less money invested than with an accumulator and the second machine would really help on longer hauls.  What would really work slick with a bale wagon would be to have a stack mover mounted on a straight truck to move the stacks from the field to barn with so the wagon could stay in the field where it works the best.
