It's definitely worth the money. Like I say, if you can't afford to throw down $35 for Pep, it might be a good idea to look into other hobbies. Because building a good suit costs a whole lot more. Plus, it'll just make your life a WHOLE lot easier, and will allow you to add something to the community (new unfolds, etc).
Also, support small software developers by buying their products! They make cool software like Pep, and should be rewarded for it!
