Use any pronto for which the editor will support import of CCF files. This includes the Next Generation or Pro remotes. As cost is an issue, I suggest you find a TSU3000 or preferable TSU7000 on ebay and that will do just fine. You will then want the corresponding editor available in the Next Generation (NG) Files section.

The pinout for the TSU1000 cable (kodak digital camera cable) can be found in the Classic Pronto FAQ.
