The G1 is not the lowest end Android phone you can get, hardware wise. The Huawei U8100 is the lowest end phone I'm aware of. It's 320x240 resistive screen and 128MB of RAM is truly crappy. It can be had for <$150, so testing your app on a very-low-res screen won't cost too much.
And you may also want to test on a tablet, like the Samsung Galaxy Tab or a rooted Nook to ensure your app doesn't look horrible when blown up on a large screen.
OTOH, rumours are that the Android tablet marketplace will change significantly soon, so you may want to hold off on a tablet.
