"Sounds like they have redesigned the skid plate from the original one that is why it is more expensive."
That's probably correct; in my past dealings with Richard Breault, he's been extremely helpful over the phone and never hesitated to answer my email questions regarding the purchase of the Bro-Tek thumb I got for my GC2310, even to the point of re-designing it for an interim version of my backhoe (which I apparently had, a late 2007 model), before the advent of the 2400 series. A very reasonable, very sharp guy. (Visited him in Miramachi several years ago, where he & his wife were very accommodating.) If you have questions, give him a call!
