700's are hard to find for some reason. 660AV and 950 come up a lot more often. I personally like the 650 more than the other Quadras. It's not the fastest or most expandable, it strikes a nice balance between the two and easier to move around than a tower model and has a really sturdy case. You can put a big monitor on top of it wwith no worries. That's why I put a Quadra 700 board into my IIvx, but I wish I could have found a 650 board at the time because it takes more memory.
