I'm with Bat, I've gotten used to ignoring the stickies and just noticed this thread!
I don't have anything to share that isn't actively being used, since I tend to only replace things when they're destroyed. However, I'm planning an upgrade soon and will be happy to share...but the parts will be low-end and 15 years old.
EDIT: Also, I assumed the thread was about stories about how we've gotten help *while* commuting and paid it forward (we ahve threads to that effect from time to time). A slightly more descriptive title might help too.
