I just got mine done also, 9 days ago. Mine's only 175' long though, so I'm sure I didn't spend near as much as you did! My cost was $4000 and that included a parking area about 40'x20'. What did the pavers tell you about sealing it? Mine said to do it in about 3 months and they would charge about $275 (I don't remember the exact cost right now). My wife's parents got theirs paved several years ago and they were told to wait a year before sealing it the first time. Since then they've had it sealed every 2 years. It's still in real good shape. I was going to split the difference and get it done in the spring, but my neighbor said it would be a good idea to get it done before winter to keep the moisture out or it could freeze and cause cracking. The ground doesn't start to freeze around here until late Dec, so I think I'll try to get it done by mid Dec.
