Evidently the original Japanese filters were discontinued/transferred to Thailand for manufacture in 2003 ...however they have fairly recently recommenced manufacturing them in Japan (2012)
I'm not sure on the shipping cost, but Curt Aigner from Elmhurst Toyota parts in US (you really have to love this guy...Ive bought heaps of parts from him) has them for about $10 each.
The top 3 he recommends are : OEM Jap Made , TRD USA [ K&N ] , and Mobil One . Here's a link showing basic comparisons: http://mkiv.com/techarticles/parts/toyota_filter/index.html
