Re: (ET) Elec-trak Digest, Vol 14, Issue 113

David,

Out of curiosity, why would you now prefer to go with a 4QD compared to 
something like a Curtis 1204 (which you can buy for around $200 on ebay)?

Thanks,
Mike

See my previous message.  :-\

I don't speak for Alltrax, but I'd have to assume that it's at least in 
part
because it's not really a mass production item.  Well, it sort of is, in 
the
sense that it's based on a mass-ish production golf car controller, but the
ET version is customized.

That said, the cost has gone up quite a bit.  I see Jim's price for it is
now $458.  When Alltrax introduced the DCX-300ET in 2004, it cost $215.

The 400 amp version, which I don't think they offer any more, was $289.

I have no idea why the price has more than doubled.  Maybe they still
haven't amortized all those buckets of exploded semiconductors.  It would 
be
interesting to find out exactly how many DCS-300ETs they've sold though.
I'd guess it would be in the dozens, rather than hundreds.

I like my Alltrax a lot, but if I were converting an E15 today, I might 
look
pretty closely at a 4QD.
