I can buy a decent 20" consumer grade bar with replaceable sprocket tip for about $35 and have a fixed budget assigned to both a bar and some chains. I was not aware that consumer grade bars were considered "junk." He was generous enough to offer an excellent quality 18" bar, for a good price, but at the moment it is more than I am willing to pay and am not looking for an 18" bar at the moment as that length runs on my 50cc saw.
To use an analogy, if someone has a fixed budget for a car and snow tires and is given the chance to buy a rwd BMW at a great price (relative to BMW) but does not leave money for snow tires and isn't exactly what he is looking for with rwd, and he respectfully declines the offer, what kind of angle is he working?
Regardless of how good a deal it may be, it does not change the amount of money in the wallet.
