Have you thought of doing a few missions, Sabi-chan? You can get points to trade in for radios or other nice things from home--that's how I got my viola. You should be able to get a record player and a bunch of vinyls if you did one.

...also, I'm keeping this quiet because it's a favor for a friend, but I have been working on setting up an outdoor film projector and screen. That way we can watch movies under the stars on these warm nights.
