Best Android Test Device?

I'm looking for a generic Android OS phone for testing apps. Is there a standard or will I need to purchase a couple of devices?

I can't imagine there being a 'standard' because each vendor has its own 'flavor' of Android, and what version they care to support. Best bet is to get more devices. If you can't borrow, check places like Craigs List for people upgrading, you can post that you're looking for used phones there too.

you should bye a Nexus One ( if you want to make app for all High End + Medium End devices ) but its little outdated , try getting a Snapdragon Device because most phone uses that , if you not look to current change of Tegra . Well it depend on what majority of device you wanna make the app for. Good Luck choosing! Or Get a Galaxy S with majority of 10 Million People alone for it.
