I believe Droid Concepts is 2.2.2 as well. Nice looking ROM. Beta 9 is the newest and 10 will be released shortly according to Devs.

Well, it's been awhile but... I've been living with Sourcery 2.2 for a day now and I've been beating on it pretty hard. No issues that I haven't already had with stock, unrooted Froyo (multitasking on the D1 is problematic due to the low physical memory).
But, it's a ROM that is nearly as customizable as CyanogenMod, but NO lockups, NO random reboots, the camera works, I don't have to toggle "airplane mode" after a phone call, I don't drop WiFi after a phone call, I can answer the phone with the ringing continuing on, etc. etc. etc.
Until GB gets "baked" a little better, I think I'm sticking with Sourcery 2.2. It's based on FroYo 2.2.2, and is about as good as it gets.
I second the Droid Concepts ROM. There are a few bugs on initial setup (i.e. you can't see the 3G and mobile signal icons without a patch), but it runs pretty slick. Sorcery is also a great ROM.
I've grown tired of force closes on GB ROMS so I'm back to Froyo.
