I'm mocking up some ideas for trying to sell a product in which customers can name their own price.
We want to get customers in the frame of mind to think "oh, a dollar a day is great value!"
Any suggestions or insight on how you think the conversion rate will be affected?
Radio button selectors to choose a price vs. button that goes to the checkout.

confused on concept
seems to be a charity website.....then you state in your comment that you are selling a product.....this will effect the terms like "buy" "purchase" vs. "donate" "give".
This all plays into how to convince the user to part with their money.
I would suggest this selection be highlighted in some way....another color or to be raised up from within the row of the others....I am not sure but I have noticed that they are normally also center in the row.
naming the levels
If you were to name the levels.....such as Bronse,Silver, Gold....It may connect to the user on a personal level and make them purchase I higher amount.
run across the page
depending on the service you are providing.....I would consider running the selction across the page working down in amounts.
setting a value
I am not understanding your concept, but you do have to show the user value is getting for each selection vs. another selection.
If it is charity.....they saying "this amount equals 2 cows and 1 goat for a family" vs. this amount buys "1 cow".
Change the denominator per option makes it confusing: ie: per day / per month / etc... Pick one and stick with it. Maybe $1/day becomes your target for the special offer?
"Give what you can..." box isn't necessary
Integrate the "give what you can" open field into the package options. You already have "other" on view 3. Just make it an input field where they can put in their desired amount and donate.
Offer doesn't line up with packages
The $39/mo or more option needs to be referenced in the packages on views 1-3. (I'm ignoring views 4 & 5 because I don't think the layout is ideal). If you're trying to get people to give $39/mo, then make that the middle options and make the box bigger with some sort of message that points out its advantages.
2nd and 3rd view layouts are better
The side-by-side options are good in your first few mockups.
Change "Buy" to "Donate"
The radial buttons on view 1 aren't clear. Buttons are good on 2nd and 3rd, but are you asking them to buy? Use donate instead.
Show others who have donated
Show pictures of happy donators along with a sentence about how glad they are now that they've donated and become accredited.
What is the benefit?
I'm assuming that you'll "sell" the benefit of donating on another page. But you need to reinforce why someone would give. Maybe something like, "Give what you can. Get __________. "
