Which rectifier to buy

I went through two OE rectifier/regulators on my 02 in about 3 years. Went to Cycle Electric in 2007, that thing is still going strong. Good choice on the C/E, I'd trust it.

First to remind all of the issue I was having with my 2009 Heritage:
My voltage gauge which typically stays right at 14vdc suddenly jumped to 16vdc (max on the gauge) and then dropped down to 12vdc.
I also got both the battery and check engine lights, however they extinguished after a brief period.
Once the bike was parked for a while (I'm guessing cooling off) everything seemed back to normal for about 10-15 minutes in operation then the voltage fluctuation started again along with the battery and check engine lights.
I got ECM codes P0562 (under voltage), P0563 (over voltage) and Speedometer codes P1006 and P1007 (not sure what those relate too, perhaps the battery and check lights).
I checked the voltage at the battery and it seemed normal at around 12.8vdc with everything off, 9.8vdc while starting, and 13.96vdc at idle.
I could never get it to fail while being able to test the voltage with my multi-meter.
I checked the 3 outputs of the stator and all three were open to ground which apparently means it's reading good.
My gut was telling me that my problem was a flaky stator but since I wasn't prepared to tear into the engine to get to the stator I decided to order a new voltage regulator.
From my research Cycle Electric regulators seem to have really good reviews and I found one on e-Bay for $129.00 so I pulled the trigger.
I got the new regulator in today and immediately installed it.
I went on a 50 mile city/hwy ride and my voltage stayed right at 14vdc and never wavered so apparently my problem was in fact the voltage regulator.
Also I swear it seems I've got more power but I don't see how a voltage regulator would have an effect on power.
Anyway, hopefully my problem is fixed.
