I've had it 2 years.
It's very easy to clean. and requires 2 minutes cleaning every 12 months.
the bulbs last about 3 months if you use it like a tv, (use every night for 3-4 hours per night.) 12 months if you just use it for friday night movies.
the bulbs are available from any bulb retailer/wholesaler, and some sound & lighting joints. it's a very common bulb (also used in stage lighting gear)
it has a brand new bulb in it. i won't be throwing any in as such (especially @ $300!?)
freight? your guess is as good as mine, probably $10-$20?
