You can for for
-AT&T BlackJack
-Sprint/Verizon Motorola Q

All have similar specs to the T-Mobile Dash. Only thing is that if you are in an area where you have crappy T-Mobile service, you may wish to look at the other carriers. But that can be said about all the carriers. If you know that if a particular services will not work in an area you are mostly at, look at something else. However, T-Mobile and AT&T have cheaper plans than Verizon and Sprint.

Hope that this helps alittle and good luck.
