What a difference a day makes...
On the suggestion of a list member, I did a search on eBay.com and ended up with the winning bid on a Square Deal B (used) with a NIB "eliminator" scale, and some extras like the low-powder sensor, primer tray, and so on.
On another bid I got a set of stainless steel calipers for $19.00 and went ahead and ordered a tumbler kit from Cabela's for $65.
Quite a day. I didn't intend to spend any money at all today. I thought I'd spend the day repairing web pages...
Thanks for everyone's advice. After I get started, I'm sure you'll be hearing from me again.
