Auditor Kerri Tompkins says the current machines are six years old, and near the end of their useful life.
"But it's very clear that both of those machines jammed as we all witnessed many times, and therefore we certainly don't want to go through that experience again."
Tompkins says the choice is to buy a new and faster model of the vendor's vote counting machines that's just been introduced, or buy a slower older model.
"We just feel that it's a slower, simpler machine. We can follow the ballots, we can read it easily. So everybody thought, again our goal is accuracy, and we felt that was the choice."
The slower, older tabulator machine was recommended by other county auditors and some of her poll workers that tried both models.
Tompkins says if approved by the county board Thursday night, her staff could begin training next month, and be ready for elections this fall.
