I saw one at the Farm Science Review (in London, OH) on Tuesday of this week. It was at the show- not on a demo, I asked how much they cost- lady explained rising steel prices and they only have a "few" left before the price increase...old price is $57,000. If you search Google for the Bale Bandit there are a few blogs out there- one basically says...they deliver it and hand you a card they says...Good Luck!! Robert is correct in his statements.
The thing I see as a draw back is if you are selling hay by the bale or someone only wants 10 bales, you need to break open the bands, then you need to move the other 11 by hand if you need another 21 or however they are banded. They are a great concept, just seem to lack product support for what you pay.
Good Luck!!
