Searching for ATTINY85 over on AliExpress and sorting by popularity renders some interesting results.
I have one of these: SparkFun Tiny AVR Programmer PGM-11801. I was thinking of getting another one or two for backup, but there’s probably no need at the moment.
Also I figured out how to put a programmer on my Pluggable ATTINY Development Board For ATtiny13A/ATtiny25/ATtiny45/ATtiny85 Programming Editor Micro Usb Power Connector (see that link for details).
|Clock||2 MHz||20 MHz|
|ROM||72 KiB||8 KiB|
|RAM||4,096 B||512 B|
The values in the above table are approximate, see the sources listed above for actual figures. Basically the $3 chip is ten times faster than the AGC but with less storage. Call it a draw?
