THB1,000 is outrageously expensive. My guess is that you took the airport taxi rather than the normal public taxi.

Alright here's the situation. When you arrive at the airport, you have a few choices to get to your hotel:

1 - Hotel Transfer

If you arrange with the hotel via bookings, they could send someone to pick you up from the airport using the hotel limo. Might be free, but if it isn't, you can expect a heavy bill. Pros: No need to wait for queues

2 - Airport Taxi

When you exit the airport and about to head outside, you're most likely to be approached by well dressed men / women in blazers asking if you like a "taxi". This ain't any normal taxi, but your high class airport limo. Depending on your destination, it would cost anywhere between THB600 - THB1,000. Pros: You get to sit in real comfortable Toyota Camrys

3 - Public Taxi

The cheapest form of taxi to get to your hotel. Head downstairs to the ground floor (not the arrival floor) and head outside. The new Suvarnabhumi airport hasn't properly prepared proper booths for public taxis, so you'll see a bunch of tables by the sidewalk. Walk to anyone of them and tell them your destination. They will give you a receipt and show you to your public taxi. The journey shouldn't cost more than THB400 if you want to get to town center.

There is an extra surcharge of THB50 if you take the public taxi from the airport, in addition to the metered fare. Also, if you decide to take the tollways, you have to pay the toll fare yourself.

Pros: Cheap. Cons: You might end up sitting in a 1990 Toyota Corolla or an old junk rusted relic of Bangkok transportation antiques
Some Tips:

Most public taxi drivers will take the Bang-Na route to get to the city. It's further, which allows them to earn slightly more milleage from you. So, if you are daring enough, tell the taxi driver to take the "Motorway" route. This route is shorter distance, and more direct to the city. "Motorway" is the name the Thai's use for that particular stretch of highway, which leads you to the Rama 9 Rd, and from there you can get to the city with ease.

The Bang-Na route shares the same trunk to and from the port. With this, you will have to bear slow traffic from hundreds of container trailers. If you're unlucky, you might experience some traffic congestion, and that can be really frustrating.
