Well you may want to consider the new Pandigital Planet tablet. According to several users at slatedroid it plays angry birds and even though it has a resistive screen it seems to support limited multitouch like pinch and zoom. If you can get a 30% off coupon from kohls the price is about $140 and may be even less with rebates etc. BTW it seems to be way better than the previous Pandigital Novel (which I own and like very much).
Here is the link to their forum on this tablet:
