Best deals on the HTC Desire HD and Desire Z?

I have been looking at the HTC Desire HD and Desire Z as possible upgrades to my current smartphone. Given that these are fairly high end units, and entail a significant cash outlay, I have been doing some online shopping too.

Best prices I have found, with an official one year HTC Warranty, are from an outfit called DCK Mobile Gadgets. The price is an incredibly low Php25,000 for the HTC Desire Z and and even more inviting Php26,500 for the HTC Desire HD.
