Weighing square bales

I am trying to track more closely what my production is, and what I am selling to my customers as well.  I used to weigh a sample of my small square bales with a hanging scale, but it had a 50 lb capacity.  Now that I am doing mostly legume and legume mix hay, that doesn't help me with bale weights.  What do any of you use for this?  I see digital luggage scales with a 110 lb capacity on amazon.  Is this a viable option, or is there something that works really well? 

 

Thanks.
