I had a request for a description of the "dremel-like" machine I was using to file down my nails, well, here it is. There is nothing fancy about it, just an old high-speed drilling machine with different tools to insert into the chuck. The 2 upper tools are the ones I use, and the one on the top does 90 % of the work, the other one is just for the last piece of the nail close to the cuticle.
It has adjustable speed, normally I start out on slow speed and increase it slightly when I get into it (and bored). It is a tedious process but I recommend doing one foot and maybe the other one the next day, or your back may start to hurt and you will not be too thorough anymore....
I would say any similar machine will do, for example the cheap ones off ebay since it requires no engine power or super speed. Get for example the one on http://www.ebay.com/itm/DREMEL-400-XPR-Rotary-Tool-With-Accessories-And-Paperwork-New-Exec-Condition-/160802040751?pt=LH_DefaultDomain_0&hash=item25708c6baf or try maybe this one, even cheaper: http://www.ebay.com/itm/New-Cordless-Rotary-Tool-40pc-Kit-Dremel-Tool-Bits-Fit-Dog-Nail-Groomer-Grinder-/170843162711?pt=LH_DefaultDomain_0&hash=item27c70bc857
If you get just any tool and it does not carry the suitable sanding tips you see in the pic (the top one the most important one, it also works just fine without the pointy tip, you can use a cylinder-shaped one), just go to your local hardware store and ask for dremel acessories and they will most likely have a big shelf with them. They are expensive, but only one is not expensive...
There you go, good luck. =)
