Tiny Headphone Amps!

[Relax]

Alright, I have seen a lot of headphone amps out and about, and I have decided to make my own. I was wondering if anybody can point me in the correct direction. I have a few requests of any designs anyone can give me that are:

Small- both in overall size and amount of parts
Cheap- not necessarily cheap as in bad sounding and poorly made
No PCB- either point to point, or a predrilled board

If anyone has any suggestions it would be quiet nice! I plan on using this to drive my 64 ohm Behringer HPX2000, which are 100mv max. I would like a design that could be used with lower ohm loads also, maybe a selector for 64 or 32 ohm loads? Thanks a bunch for your time and suggestions!

I would also like to mention that I want to build this amp. I can't find the edit post button either! haha

64ohms is rather low impedance. 600ohms is a very high impedance. www.head-fi.org has a rather nice DIY section that I would check out, or http://www.headwize.com/projects/ . I'd suggest a cmoy.

I started on the Cmoy at this site:

this guy lays it out very nice and simple. Ordered parts for two via digikey 45 minutes away.

These are the best places to start.
The Cmoy is nice and simply if this is your first amp.
