I am pretty amazed at the current rate of development of new Apple ][ conveniences and devices. It is worthwhile to look up from a project to see what others are doing every once in a while.
VGA adapters for the Apple IIc and IIGS seem to be hot right now.
The Nishida Radio Disk II adapters are gaining more and more features, including a nice looking web interface!
Big Mess O' Wires had added Apple II support to the Floppy Emu Disk Emulator.
It's impressive to have a microcontroller with more power than the Apple II strapped on the back of it. Although it does feel like cheating sometimes...
I merely managed to find a switch that perfectly fits the Apple II keyboard encoder for enabling lowercase once the character ROM is updated. It is labeled "ONLEDA MTS-202" and is a knock-off of some old high-quality switch, I'm sure. Good ebay search terms : Right DPDT toggle switch. Just take note of how the pins are oriented to make sure you get the right ones. I'm putting mine away for a rainy day.
A new style of Apple II prototyping card popped up on ebay too. Had to buy one.
