I'm in the Philippines, too.  I ordered from ZH last month and I got the order in 4 days via Fedex.  Cost to ship will be given to you when you check out.  You will definitely pay taxes with the amount depending on the customs examiners mood on that day.  You will also have to pay additional fees (storage, IP, etc..).

I recently ordered again which hasn't gone as smoothly as the last time.  I put in an substantial order last April 1 which which was supposed to be with me in 2-4 Business days.  Based on the tracking info, it shipped from HK April 5 and arrived in the Philippines April 6.  It's been stuck with DHL/Customs to this day.  I've called DHL a couple of times and it looks like I'll have to jump through a couple of hoops to get my package and might loose an arm and a leg.  I tried to contact support to get a copy of the documentation that's with the package for when I deal with customs but response has been slow compared to before.  Sad thing is, the units have undergone a price reduction twice (I think) since I put in the order.  It's a pretty significant amount if I add the savings if I had ordered later to the lost time mining.  If I do order again, I'll use my consolidator in HK.  It will cost extra but at least I'll know what I'll actually be paying.  Hope you have better luck with your order.
