If you haven't checked it lately, Dennis Bournique's Plan Finder at prepaidcompare.net has lots of improvements, and is pretty wonderful. (Thanks, Yeswap!)
I don't know how many minutes/texts you might need, but other possibilities include
Tello (Sprint): $16-19 plus tax/fees, for 200-to-unlimited minutes.
Twigby (Sprint with limited VZW roaming), $19 plus tax/fees inc. 200 minutes, stepped up from there.
Red Pocket (VZW, 12-month) $19.08
Red Pocket (Sprint, 12 month, via ebay) $19.08 with 5 GB
Gen Mobile (Sprint), $20 + taxes
None of these beat Chelle's suggestions for simple month-to-month cost with a particular network, although the Red Pocket Sprint plan has more than twice the data for a few dollars more per month..
Re: Plan Finder-- you can designate carriers, hotspot requirements, whether iOS imessage is supported, roaming, 2G fallback-- and each provider line can be clicked on to get more info that isn't easily charted, including whether taxes/fees are additional or included.
