I got ExpertPath recently to use up some CME money that was going to expire. It's alright. Similar to pathoutlines, except the pictures are better quality and actually load*. Doubt I'd spend $900 of my own money though. Libre Pathology is another nice site, and free. Best part is it gives sample diagnoses and micro descriptions, which is perfect for those ditzel cases where you're not sure how to phrase something.
* I remember being at a conference where Mark Wick was a speaker. I was like "Hey, it's the guy with the ****ty pathoutlines pics!" Nothing against him as a speaker or pathologist, but it's hilarious how his pics have an attribution and they're always low-res with weird color balance.
