I've always found the Buddha cards very good. I had one of the original Buddhas that worked very well and I still have a Catweasel ZII S-Class which incorporates a Buddha. I am selling the Catweasel actually but I no longer have a Zorro equipped Amiga to test the card in (it hasn't been used for over 5 years). Taking this into account I'll accept quite a low offer for it.
The Phoenix edition Buddha has some nice extra features like the clockport and flashrom so all in all it's a good expansion for an A2000. The quality of Individual's stuff is always very good so AmigaKit's price doesn't seem too bad to me but I live in the UK so no exchange rate to worry about.
