In the past, I had episodes of working for Taiwanese company as sales rep, working in cram school as an English teacher (btw I am Polish) and now being a student on scholarship as well as owning my own business, I think I have enough knowledge to help anyone get an idea of what to expect financially when arriving here. I am also married to Taiwanese lady, so I can give you interesting perspective from local point of view (and guides how to buy things cheaply) as well as from foreigner point of view.
My pure motivation about writing this blog is to help anyone who plans to come to Taiwan and post how much things cost. It doesn't matter if you come here for traveling, study, family visit, work, or any other purpose, I will try to write to all the audiences in a simple and not difficult to understand way. I did write a very short guide on expenses in Taiwan a few years back, and it was quite popular search wise, so I have decided to make this niche blog. Also, in my articles, I will usually mention 'Where to Buy' especially for things that might be hard to find locally.
Did you notice that I wrote niche in italic? My goal for this blog is not to make it large and write about everything in regards to Taiwan, but rather - how much money will you need to stay here. It will not be updated daily, but more like weekly. I believe that if I can write one good article a week, for a year, then we have 52 articles in a year, which is a good enough to cover most important matters that I think of.
If you ever need some quick price information on anything that I did not post on this blog (for example, "Is there any Fridays in Taiwan and how much a good steak cost?" - feel free to let me know. If the inquiry is interesting enough, I dig up some info and write a whole article about it.
Edit (Jul 18, 2011): I will start adding restaurants overview to the blog, together with my verdict and scan of menu (if possible)
