LOL I have been to Lowe's and Home Depot about 20 times a piece already this past week. McMaster Carr was my bestie 2 years ago when I rebuilt my old Yamaha Waverunner from the ground up. However, and for whatever reason, I just really like the BRS float valves. I am a bit neurotic sometimes.....ask Rob.D
Plus I just found out that BRS offers $5 shipping....so maybe the group buy isn't as beneficial as I thought. But.....the offer still stands!
