Not sure if any of you may care, but here is an update:
I ended up getting both, the 2.33 for $800 and the 2.2 for $850. I was able to use cashback on the 2.2 since the seller put it on ebay for me. I liked both models, as well as my old mbp too. The LED screen was definitely brighter, but at times I thought too bright.
It was certainly a difficult decision, but I decided to sell the 2.2 and the my previous one. Made a nice profit on the 2.2, and sold my old one for $850 (but I kept the 320gb HD), so I definitely came out ahead.
Just wanted to say thank you to everyone who helped in this thread!
