Which type of device should I purchase for developing? What are advantage and disadvantages if I purchase Android developer phone?

What are the payment modes available for purchasing Android Dev phone and creating account?
I know only one mode credit card, Tell me if you have any other mode than this?

I have the same question.
I think the best way to develop is to use the Android Dev Phone because it's hardware-unlock.

Besides, it's possible to flash it with new Android version, at least until 1.6 (see http://developer.htc.com/adp.html#s3 ). I think commercial phones can not be flash by user...

I would like to add some questions :

Q1 : Do you know if Android 2.0 will be available on the Android Dev Phone 1 ?

Q2 : Does Android Dev Phone 1 have the hardware capabilities to support multitouch ? I say that because multitouch has just been implemented in Android 2.0 and the Android Dev Phone was release when it didn't exist yet.

Q3 : Is it possible to flash Android phones buy in a market ?
