What is the price you are trying to beat on the Frontier?
Are you wanting the same quality as the Frontier? and how much cheaper in quality and/or price are you interested in going? Help us out a bit.
If the rear blade you get doesn't match the I-match, you can get a welder to make it fit. When I updated my older Deere blade, it only cost me a bit more than $200, but it now fits the I-match and I am happy with it. /forums/images/graemlins/smile.gif
