I was thinking about getting an avr-isp to use to program my 328 (Duemillinove/UNO) via ISCP. Looking at Ebay I see a lot of cheap options like this:
I notice that it programs the Atmega 168, Atmega 1280, Atmega 2560, but NOT the Atmega 328? Is there something special about the 328 that it wouldn'tbe on this list?

Just to clarify... if I picked that up, and a 6 pin adapter I could program a 328 directly? i.e. Not via usb/serial built in to the arduino bootloader?
I was thinking about getting the above mentioned avr-isp, and then this 10pin to 6 pin adapter. Will this work to program an Uno?
Yup, I use that one with the same 6-10 pin adapter. Works with everything. I use khazama programmer: 2012-08-14_1550
Mainly I use for http://www.ebay.com/itm/ATTiny48-88-ATMega48-88-168-328-Breadboard-Adapter-Kit-/280822197407?pt=LH_DefaultDomain_0&hash=item41624eac9f these adapters (also there are some small ones for attiny85)
I have an a Leonardo also. One problem I see with it is because the USB/Serial is on the same chip that you program, it drops the USB connection every time it reboots. I end up with /dev/ttyACM0 and sometimes /dev/ttyACM1 depending on timing. With an ISCP programmer like this, I could use the Arduino IDE to upload code with the avr-isp instead of over USB serial, and avoid the serial port name bouncing around?
I assume the Leonardo and the Uno use the same ISCP (JTAG?) interface? It's just a different chip to compile to?
I am not sure about Leonardo, but how do you will set Arduino IDE to use this programmer? this is an avr-asp I don't think is supported.
Ahhhh good catch. Looks like Arduino IDE 1.01 supports it though?
Well, I am not sure, I am pretty happy with khazama so I didn't tried anything else
