Grainger offers the Stanley 8-1/2" Linemans Pliers, model no. 89-864, for $7.79. (Amazon charges the same for Prime members with orders of $25 or more.) Choose in-store pickup to avoid the $10.48 shipping fee. That's the lowest price we could find by $9, excluding the below mention. They feature a 2" jaw length, 1/2" jaw width, and ergonomic handle.
A close price: SIM Supply via eBay has them for $8.81 with free shipping.
