Alltel Prepaid-need to choose a phone! Moto E815, LG AX245, or Moto W315

I'm planning on signing up for Alltel Prepaid soon, and I'm trying to decide on a phone. I'm considering the Motorola E815 ($129.99), LG AX245($79.99), and the Motorola W315($49.99).

I'll be using the phone in SE Minnesota, and doing a lot of traveling to the Rapid City, SD and Jackson, WY areas. I'm most interested in the LG AX245 and the Motorola E815, as I would like to have a camera phone. In my research I've found a lot of information on the E815, but not so much for the LG AX245. Some of the areas in SD (Black Hills) and WY that I'll be in will tend to have poor reception due to the terrain, and I'm also curious about the necessity of having analog capability (the LG AX245 and Moto W315 both are tri-mode phones). I'm concerned that many areas in the southern Black Hills (near Custer, Hill City, and Mount Rushmore) may have better analog coverage than digital coverage.

So what would everyone recommend? Cost is a concern, and I'd really like to save $50 by going with the LG over the E815. But, if the reception of the E815 is going to be vastly superior to the LG, I guess I'd rather spend the extra money.

Thanks much!

 

After a little more research, I dug up these bits of info:

Those posts are from this June 2006 thread. Is this likely to be an issue for me? And if so, would the W315 or LG AX245 be better in that case?
