That much over the original estimate?
If I go the pay software route and follow the recommendation I'm getting to go to more of a dedicated set up (which would help in times of high traffic), I could see it being close to $800. I don't think I'll be going to quite those links. I know I'm not for $800. Just trying to figure out the best bang for the buck I guess.
ETA: "Times of high traffic" meaning not necessarily the Woolly, but traffic of any other domain you might share a server with.
