A Visa Run and a Very Difficult Decision

It's been a whirlwind couple of days. My last day in Ko Chang was relatively uneventful. I spent most of the day relaxing and planning a lesson plan (introduction to Sensation and Perception) for a demo lesson I was going to do for a very fancy job in Bangkok.
The next day I left on a package deal to make a Visa Run to Cambodia. The "free visa" you get as an American in Thailand only lasts for 30 days at a time. You can renew it 3 times in every 6 month period, but doing so means leaving the country (if only for a minute) and coming back in. Because I had an interview to get to, I did the hop-out hop-in scenario. Everything I had read warned of scores of child beggars at the border. Of course there were some, but certainly fewer than I had expected.
In general, from what little I saw of it and heard from other travellers, Cambodia is a much dirtier less "pleasant" place than Thailand. Once you cross the border everything just seemed dirtier and run-down. The difference wasn't striking, per se, but certainly noticeable.
The whole process of getting a Cambodian Visa, getting across the border, and getting back took about 2 hours and 35 dollars (although it should only have cost 20, I later found out). This, of course, doesn't include transportation, the grand total of which cam out to another 30 dollars or so from Koh Chang to the Cambodian border and then on the Bangkok.
Having found out that a pre-purchased 2 month Visa costs only 40 dollars with no day long grueling visa runs, I wish that I had planned ahead a bit better...
I arrived in Bangkok at about 7 pm, checked in to my hotel, and found an internet shop to type up my lesson plan. Early to bed, early to rise, and before I know it I'm on my way to Wells International School in Bangkok. Quite the establishment.
Wells is a secure campus, with gates and only one entrance during school hours. It has an indoor basketball court, pool, delicious cafeteria food (including vegetarian options), air conditioned classrooms, an auditorium, and enthusiastic staff. The Headmaster was a wonderful man who welcomed me warmly and made me feel very comfortable at Wells.
The class I taught was wonderful, and quite small (12 students). The students were shy but well behaved with good personalities and seemed to know each other quite well. I had a great time teaching the class, as the subject matter was something I am very interested in (psychology). Overall the school was great.
Then, he told me about the pay. A clean double what I would make teaching in a village. More than enough to live in the lap of luxury in Bangkok, generally wanting for nothing, and still saving about 500 dollars a month.
But, it was not meant to be. After talking to Trevor, and also Daniel about it, I decided that I would turn down the job... painfully. In the end, I did not fly to the other side of the planet to teach at a highly westernized school. I came here to learn Thai, teach Thai kids, and even live in a Thai village, which is what I will do.
Today, I will go to an office in Bangkok sometime in the afternoon and sign a 4 month contract to teach in Uthai Thani. The pay is less, the classes are larger, and the village is very remote. But, I will be teaching an age I am much more comfortable with, and getting a genuinely "Thai" experience. It's not Wells, but it's one of the best jobs I've seen in a village.
In the end, it's only for four months, and jobs in Bangkok, even fancy high-paying ones, are a dime a dozen. I wasn't even looking for a job in Bangkok and I found a great one. If I decide I should have worked in the big city I can just do it in May...
