Yes, as kermit said, if someone has placed a high bid, it will automatically continue to outbid anything you bid that's lower.I would have waited a little more and bid some more, but I've now got a vehicle insurance payment check pending and it would be BAD if it bounced. That's the primary reason for the $100 self-imposed limit, including shipping, I'm willing to pay, to protect that.
I wonder how often these 530 units show up on craigslist, and what they go for. I have no problem driving to one of the small cities within 100 miles of me to get one of these.
Check on craigslist and see what you find. However, I strongly suggest you not rule out a PL-570. While not quite as plentiful as 530s, it was a better table and less well-known than the 530, so you may not have as much competition.
