I’m a fan of the new and notable feed on the main page myself. KEXP is also a great source of new acts which are typically not on major labels.

Ploopy trackballs and mice are awesome. Get one!

You probably already know this, but there is a collectors market for player pianos and other automated musical instruments. See AMICA in the US. (Not sure about non automated ones; heavily depends on the instrument.)

There are some nice decaf coffees out there if you like coffee but don’t want the caffeine. Almost anything using the CO2 process will be pretty great.
