or you can look in the trading section, there are a few threads that have already converted games. if you do plan to make your own eboots though, you should use PSX2PSP 1.4, that's the newest version.
They all work about the same, it's just psx2psp has a nicer look, and is simpler to use for beginers. impalerpsx is a good one too.
Also, if you're making custom eboot files then google 'popstation image packs'. There's a great site that has user made images for just about every psx game.
I use Popstation GUI betaII in conjunction with popsloader. Have tried premade eboots before, for example, hako's, however they appear to have some errors, like medievil 2 and spyro not having BGM. This is because they have been converted to EBOOT without using the CUE file, this holds the key info such as BGM and SFX and the general smooth running of the game.
