I think you will find the Sams ones will work fine, but they will probably only last half the time. If money is an issue right now (in a pinch and need batteries) buy the Sams ones, but beware you might have to replace in 3 years. If you have the extra $, just go get some real good interstates, or other top name brand. After all, I have had 2 of the biggest batteries Tractor Supply carries in my deuce for 2 years now, and no signs of age. I dont drive it that often, maybe once or twice a month depending. They were $75 each 2 years ago.
I think 120-200 might be a littel high.
