Is the "Action Replay a good modchip for PSX?

[Tooncenator]

Im looking for a modchip for my PSone. Please post if you have personally used a modchip that you dont have to solder. I found the "Action Replay" modchip that goes on the back of the PSone. Also I found one called the "PlugMod". I looking for suggestions for buying a modchip that I dont have to solder. Thanks.
