"You can purchase a single copy of Enfish Find at http://www.enfish.com/Products_buy.asp"
Yeah, the Enfish web site has some conflicting text. In one place it says it's only available by itself in lots of 50 or more, and yet you CAN buy just one copy.
I've actually been using X1. It's heritage is, supposedly, Lotus Magellan (it's from Bill Gross' Idealab). It's very small (the download was just over 1 MB, as compared to Enfish Find at more than 8 MB) and quite fast (on my old 466 Mhz laptop, it indexed all, and I mean ALL, of my Outlook and OE email -- to include attachments -- contacts, and files in less than half an hour -- and I have a TON of documents, several GB worth). It's search is fast (I still like Infoselect for it's fast search). The major downside is the price: $99. And, so far, it doesn't search Infoselect files -- which is where I have archived lots of text data over the years.
I'll give Enfish Find a try, too. If it does what X1 does for half the price, well...
I've seen some reviews from "former" Enfish users who rave about X1, though. Interestingly, until recently, X1 was called Find, too.
