Try http://www.hostip.info it
is reasonable accurate in most cases and
hell it is for free. It depends what you need it for of
course but it is
far better than nothing.

64.29.76.9, your mauigateway.com pops up correctly as
Honolulu.
205.166.249.10 is guessed to be somewhere random in the US.

The problem with this one is that they are still gathering
data and they
depend on user input, but it looks pretty accurate to what I
have found
out.

Most of these kind of databases rely on user input though. I
am quite
sure that Google, using their search thing and especially
Orkut has
quite some info on this. Shopping Sites like Ebay and Amazon
of course
get their shipping info for free and thus can pretty much
pinpoint the
city correctly after $x percentage of customers bought from
there.
Problem in the end is of course when there is a huge pool
and the
end-users change a lot, but then the country is accurate
enough already.

The problem with their "user input" is that the
result they return is 
typically the ISP NOC location (in my case 200 miles south
of me, about 
halfway across the country).

If I "correct" this, then suddenly all my ISP's
users appear to be 
located in the same town as me. Which is probably more wrong
than them 
all appearing to be where they've guessed the NOC location
to be.
