I've finally decided to get a modchip for my PS2 so I can play some imports. I looked at the flip tops & disc swaps, but they seem like too much trouble and I'd just like to be able to put an import disc in there and play it without doing anything else.

I'm currently looking at the DMS4 Pro chip but I'm torn between getting the solder and solderless versions. I haven't had much soldering experience aside of removing a few batteries from some circuit boards, so the idea of getting a solder chip and installing it myself kind of scares me. The solderless chips look attractive but someone told me that they aren't as reliable as the solder ones.

Can anyone with some mod chip experience set me straight on the basic pros and cons of solderless chips. Also, is installing a solder chip something that's hard to screw up, or should I get some more soldering practice in under my belt before I try and put one in?
