Things I might want

Some things that aren't too expensive that sound potentially interesting or useful, but I'm not necessarily clueful about:

• Headphones. I'd like something comfortable and with reasonable, but not necessarily audiophile-grade, sound quality for work. But I have no idea where to start, or even where to start looking.
• Virtual private server. There seem to be several places online that will sell me a virtual machine for $20/month or less. I could do this, set it up to be a mail/web/blog server, and come up with a domain name. This gets me around feeling vaguely uncomfortable with still using an MIT address as my primary email, plus all of the cool kids have their own domains. Googling "virtual private server" and clicking on the ads is actually useful; any recommendations for a service, or a domain name?
• DigiKey bits. It looks like I can build an extremely low-end DCC controller for my model railroad from a pot, a PIC, and a chip that can take the 5V TTL output from the PIC and send it out to the rails at 12V, up to 1A. I had a part from 6.115 recommended to me, but it's been discontinued.

More fun with FlightGear

"Good evening, ladies and gentlemen, this is your captain speaking. I'd like to welcome aboard DaveAir flight number 1700, with non-stop service from Los Angeles to San Francisco International Airport. We'll be flying at a cruising altitude of 25,000 feet, with a flight time of approximately 45 minutes.

"We would like to remind you of some...special features of our aircraft. While our flight crew is good at finding where they're going, we're necessarily not so good at getting you there. As such, there may be sudden movements in the cabin while we attempt to find our course. If needed, please make use of the bags the flight attendants are handing out to contain your vomit. Also, please feel free to use the blue button above your heads to contact the flight crew if you happen to notice that, for example, we're attempting to land without lowering our landing gear.

"The flight attendants will be through the cabin shortly to serve your choice of beverage. We recommend something that will calm your stomach. Thank you for choosing DaveAir, where we keep costs low by using amateur pilots. Sit back, relax, and enjoy your flight."
