I'm right in there with Dumore also..an old standard - a bit pricey. An old
German Engineer told me they were junk, but I have never found that to be
true. We uses sensitive presses like the Dumore for drilling and milling  to
middle layers on multi-wire boards. They will remain tight and accurate
until someone tries to do heavy work on 'em. They are definitely for the lab
and not the shop.
There are only two models available however....try here:

Another thing that has worked:
- when the budget is small, almost any of the small bench-top presses can be
used for this. For example, one that works well for me these days is a $59
Delta drill press sold at hardware stores and home centers. All I did was
put an upgraded chuck in it and - voila! I have drilled hundreds of holes
from 7 to 60 mils, the switched over to a circle cutter, then back to small
carbides with no problems. Rarely if ever do we break any drills. Of course
tramming or squaring the table well and using Vee-blocks for drilling tubing
are a big plus. Good methods are often more important than the cost of the
tools used.

And another...

When building my pcb machine, the first function was to apply paste from
syringes. Then I searched and searched for a combination of parts to make a
drilling head. (Some out-of-date info & pix: www.clicsystems.com )
At one point, I tested a battery powered dremel brand tool for which I made
a rigid circular clamp, similar to the syringe clamp, but larger (I later
made an adapter to hold the syringes also with the same clamp.) I purchased
dremel's 1/8 collets, which now hold 1/8" shank carbide PCB drills in the
dremel tool.
This set-up proved to be dollar for pound, the best. It drills countless
small holes accurately on center and never breaks a drill. Of course, rpm,
feed rate, tight 3 axis feeds and good work-holding have a lot to with it
too. I can't speak for the toy drill press that is sold for dremel tools,
but I have found that the dremel rotary tools themselves have been getting a
bum rap. They are tighter than one would think from all the bad publicity
they receive.

Too bad there's an ocean betwixt, or I might have volunteered to drill your
tubes for you (no off-color punning intended.)
