ya. I've been trying to research them. They put them on ebay quite a
lot and nobody has complained so far, but i'm not ready to plunk down the
cash just yet.
I'm looking for a PMA of some kind .. or maybe some kind of marine rated
alternator that can handle getting wet.

Although I have no personal experience with them I would also look at the
250 Amp twin rectifier Delco CS-144 found here:
http://www.alternatorparts.com/externally_regulated_cs144.htm I am not sure
if it is any good but I plan to get one some day to try it out. If you go
this route let us know how it goes as I want to know if they are worth the
money.

Prestolite/Leece Neville model 8SC2202VCA is 185 anp with external
cooling duct. 086-215-200-JH is I believe a 200 amp 28 volt unit that
will work just fine as a 12 volt unit as well.
The big Leece Nevilles were used on ambulances and some large
over-the-road trucks.

I found my solution, and just got it this morning (8/23/07)
Decided on the Leece-Neville 7706AA.
It's externally regulated, bi-directional, rated at 165amp@7000rpm,
135amp@3000rpm.
Only problem was, the price quoted new from my auto electric guy was
$500+.
Went to my auto parts guy, and he got me a Remy rebuild of the Leece-
Neville 7706AA for $299.95 plus tax, got me out the door at $317.
Got him to let me give him an old Delco alternator I had lying around
as a core, so I avoided the core charge.
The Remy part# was 20007.
Had a round shaped tag on the alternator that had the "Remy" logo,
below it said "20007" and below that said "Remanufactured".
It also compared visually with the diagrams of the Leece-Neville
7706AA I got from the Leece-Neville website.
Took it to my auto electric guy to have him check it, and get a pulley
for it.
He said it more than met spec through the rpm ranges, and he ran it up
for a few seconds to 175amp.
So I now have my bigger alternator for when I decide to grow the size
of my battery bank.
