1. Get a sander, and take all the shine off your iron.
2. lightly coat the pcb with flux
3. run the tip down the pins until all 4 sides
4. Madly dump flux and solder on your iron to get it tinned again
Thats how I do it.
I regularly solder 100 - 180 PQFP parts.

I only have one from Marshal that was a sample.
You can get up to $15 of samples from Marshall. Why don't you get some
Atmel DataFlash (256kbyte/512byte) and the 2313 from them.

Just a second...
