Don,
I have two HP 200LX computers that I still use from time to
time. I think I have a half a gig card in the one - amazing
when I think of the IBM XT and it's huge 10 MB hard drive.*
In any event the HP 200 LX is very well made and has lasted
this long. I wouldn't think there would be a huge
difference between the Singapore Rollie 35 and the German 35
but I would know for sure. I own a German B 35 and that is
my only frame of reference.

I have a vague recollection that one of my LX models, (I
went through the 95 and 100 before ending up with the 200)
had to have an in-warranty repair.
I received from Thaddius a couple of years back a free
software patch that's supposed to allow it to see much more
than the 10 MB I have in it now. I know for sure that it
didn't see the microdrive when I tried that and have been
afraid to install the patch without more communications from
them.
Anyhow, do you have an add-in driver for your expanded
memory? (Thaddius used to add memory and increase processor
speed, but they did it by tearing into the guts of the unit
and I just wasn't comfortable with that.)
I have leaned to just use alkaline batteries in the unit.
Rechargeable batteries, at least a few years ago, would only
last a few cycles of charge/discharge, and had a lower
capacity, by far, than regular alkaline batteries. I now
keep it on AC power. I have a nice battery check program
that works well and I use that from time to time.
The HP product I miss most is my HP45. It developed a
display problem and after a lot of thought I just had it
destroyed when I was packing to move in October, 2007. I
haven't much exercised the RPN and scientific features of
the 200LX but it's not as nice as those on the 45 which has
a better keyboard for that.
When I owned my own company I was able to upgrade as new
things came along and went through all the Sharp Wizards,
and all the HP products with the 200LX being the last. I do
have an 18C and that's the one sitting on my desk most of
the time.
Back to the issue of estimating distance, it's been a long
time since I had a camera that required that but when I did,
I could do very well. I also went for many years without an
exposure meter, just using the paper that came in the film
box. I still have (just re-discovered) my GE 8DW58Y4 which
is a little sick, but it served me well with my 2.8C when I
lived in The Netherlands in 1963. The needle has no pivots,
just held by the springs, and it tends to fall against the
scale in some positions. It has always seemed to have a bad
cell but it gave me good exposures. I don't really know the
model number other than that long one just above.
*About hard drives-
I used to sell Molecular brand computers. They had a 30 MB
hard drive that was about the size of a VW engine. I also
designed an adapter to add hard drives to that first Xerox
CP/M computer. In connection with that I contracted to buy,
from a new company, Miniscribe, 1,000 10 MB Rack and Pinion
drive (Their special claim to fame) HD's for about $1,200
each wholesale. I never bought them all but those were the
days when 10 MB was a big deal.

One really has to think about this in these days of
cheap 1Tb drives and 64Gb (and larger) finger-sized flash
memory. The prices for new computers at Fry's lately have
been rather shocking: one can buy an economy computer for
not much over $200 and a deluxe computer for well under
$1000, that is, complete with KVM. These also have RAM in
huge quantities which would have been unthinkable only a few
years ago.
