The maximum set strength is 2400, but I'm not sure how strong Shredder really is in comparison to other programs, especially running on the iphone processor.

I'm definitely interested. I'm sorry I haven't been to club in a few weeks. Work has kept me very busy. I should be there next week.  See you all then!

As I am still trying to feel my way through some basic tactics and strategy I was looking for a cheap chess program with good feedback.  I downloaded the Shredder chess application for my IPod Touch (a great b-day gift from my family) and have been thrilled.  The interface is very easy to use, allows for easy setup of positions, and gives move my move feedback that does a decent job of evaluating whole board position (by my humble estimation).  It also gives an estimate of ELO rank. Although I understand it can be off by quite a bit, it gives a nice gauge for progress. Additionally, it comes with a nice set of problems.  Total price tag is $8 if you happen to have an IPhone or IPod touch.  I understand they have a suite of programs for the computer, but I have yet to check them out.
