i've also owned "jwr.net"
as probably a few other members here, have as well.
theo pointed out how prices have risen, this is true!
when i acquired the domain, it was in feb. 2004.
price was $160.00!
this was only 12 months and a couple of weeks ago!
the year before that, in 2003, they were $80
and in 2002.....$40.00
the value rises because of........
development of domains into websites
sales of domains to endusers
auctions
the remaining in circulation, get circulated, as the price goes up and the availability diminishes.
therefore, the longer you hold them, the more valuable they become!
currently most are used by resellers as "quick currency sales" to purchase other domains.........when there are no enduser contacts.
if you got it for $300 > $350 then hold it til 2006
it should be worth $500 minimum then
