i've had 3 red tops. 1 died well after warranty, 1 died shortly after warranty and one gave me $75 back in pro-rated $
i went with a single rebuilt red top almost a year ago and it's performing as good as the other 3 I had. all through winter and winching and winter camping and sitting for weeks on end while I ride my bike. Also powers my new 500watt stereo no problem.
best of all, it cost me $75 (free swap for my pro-rated warranty). i'm planning on getting another to fill the dual space under my hood. I didn't expect it to last 6 monts so I am pleasantly surprised.
