Seriously, here's what you need:

It's a Dremel engraving bit. Use it in a hand drill. The shaft is thick so it won't break. The tip is the perfect size for PCB holes (in fact it's a little too small for wire so you may have to ream those holes out a bit, but it's great for component leads). The tip is that tiny ball on the end. And actually, I'm not 100% sure which size I use, so check out all the sizes before you buy. I got mine in person at Home Depot so I was able to eyeball it.

I have used the same bit since I started about 20-30 PCBs ago. And no need to replace any time soon.

Get it!!

I used the same thing for a while now. I recently got a set of bits from Drill Bit City, but haven't tried them out. You're right about the hole size for wire. It's usually just a little small for tinned wire, but close enough.

I use one of these. It'll never pay for itself in strict financial terms, but it was still worth every penny.

I don't know if anyone has mentioned this yet, but... use a small punch (I'm not sure if this is the correct name) and a hammer, to mark those spots. Then, when it comes to drilling the board, the dremel/hand drill/whatever won't move as much. It kinda locks the drill in place.

I use a regular dremel and do it by hand. I admit it's not what people usually use but it does the job cheaply. I can drill with a few degrees o angle inclination and I dont have any problems. haven't proken the bit yet!

I put the PCB on my drilling board on my table, get down on my knees so that it's at eye level, and commense drilling. obviously eye protection is a must

Thud... :P

There are cheaper options, but that's the only one I know of with a proper stepper motor 3rd axis - most of the alternatives use a solenoid and tend to break the router bits. And they're expensive too!

Holy thread revival etc.

Speaking of cheaper options, I spotted this recently:

Under £300 total for a CNC PCB drilling system. You have to assemble it yourself but it doesn't look that tricksy.

Center punch followed by simple dremel drill press with the engraving bit mentioned below. Cost is under $100 and saves you countless hrs of time. I have tried EVERYTHING and this is by far the easiest for the $$$
My tender heart bleeds for you, idiot.

could someone say exactly what engraving bit they use?  is it the 106?  I have been using a #60 bit in my good ol' craftsman rotary tool clamping the board down to my work bench and free handing it.  Its worked so far but I would like to move towards a more permanent solution as I get more and more into making my own PCBs.
