A little bit of searching on DigiKey revealed some dual row 0.1" header pins that aren't as expensive as the ones I had been buying. Here's the information:

BTW, these are gold plated. The tin version are even less expensive.

Post often, reply more!

I get my stuff from Digikey too. I look for the cheapest at the time. I have been caught once with pins that are too long. Not by much, but longer than the depth of the IDC connectora I use...

Just be careful to double check everything.

my local fry's electronics sells these for fairly cheap. a bag of 5 pcs dual row 80 pin headers (40 pins on each side), can be broken to smaller sizes, for $4.

What Fry's utterly lacks is breakaway FEMALE headers ...

Last few times I searched for them, I couldn't find those at DigiKey either. Anyone got part numbers?

i haven't looked for female headers too much, mainly because i'm always using the ribbon cable thingies as the female part.

electronics goldmine has a few:
16 pin (2x8), 20 pin (2x10), and 34 pin (2x17) female headers (all $1 per piece)
but they don't seem to be easily breakable to different sizes. also I think they have a $25 minimum order

I have never seen female break-away headers, the regular style should be easy to find at Digikey and Mouser. Most of the stuff I buy comes from Mouser because I don't like the idea of the surcharge if the order doesn't total above XX dollars, not that filling the $25 is hard to do, but my last order from Mouser was indeed less than $20 after shipping, and I bought at least 4 of everything I needed.

The breakaway headers are nice because you can use them with breakaway male headers for board-to-board connectors.

Re "never seen them" ... I don't have an STK500, but the pictures of them which (e.g. in the STK500 user's guide) I've seen show the breakaway type being used to connect the daughtercards.

3M series 929 0.100" Boardmount Sockets are available in 1 or 2 rows.
They appear in Digi-Key Catalogs T072 page 211 or T073 page 218

They are not break-away but can be cut with a thin Exacto Saw.

Dual Row, Tin, 72 Contact p/n: 929975-01-36

I did finally see some on Mouser's site the other night. The STK500 that I have does not have the breakaway style headers.

The non-breakaway style has never given me any issues with cutting them down. Simply pull out the contact, and grab your diagonal cutters and cut. File or shave the end smooth.

Mouser has the same header for about $2 bucks :)
