There are lots of small GPS receivers in the $40 to $80 price range, but are there any that have some built-in memory (or maybe a SD or micro SD socket) so that they can perform coordinate logging directly to memory for retrieval at a later date?

Sparkfun's Logomatic v2. It's the only fast small logger I know of, and I've been looking for them too. It uses a micro SD card for up to 2 GB and takes
57600 baud and maybe higher.
Note, this is a serial logger, you need to add the GPS module, an ideal being Etek's EB-58 or newer equivalent, as it does 5Hz logging and from what I've seen does better that SiRF 3. (It's MTK).
Trying to find a commercial unit to do what those two things can do might be impossible, and if you did they'd charge you massively because it woult outdo any commercial unit by a wide margin. The two modules are relatively cheap though, and easy to put together, you just need a case and a Li-ion battery with a charge circuit. (I think Logomatic even includes the charge circuit).

I have to add this... I tried two commercial types, and found that both relied on proprietary closed source code to fetch the data from small flash eeprom memory. The required programs were flaky at best, and wouldn't run on W9X at all. Forget these units if you want fast versatile output, and do your parsing direct from NMEA data. This way you're not bound to any specific hardware, OS, or software. So long as you can read the Logomatic's SD card either via USB, or by moving it to a reader, you have data.
Self-reply, as method of repost. Message failed to appear on Giganews despite being posted there. It showed up on Easynews, so answering on Easynews might make this show up on Giganews. If not I'll leave it, it's too big to keep hammering it in.
