It all depends on how much you want to pay (now and later)! You can get the NAPA GPR109 or the Sorensen MR99 for probably $18 or so. Or you can go stock for probably $60. Both of those options will probably be somewhat short-lived. I'd get the Stancor 586-902 for about $45 from someplace like Allied Electronics or NewarkInOne. It has been on my truck for at least three winters now with no problems. Cheers!
