I've had 4 ISP's (7 if you want to get technical)
1. Midwest Communications
Linky Aug 96-Aug98 Good ISP, just not local. $19.95 for Unlimited.
2. Internet Revealed
Linky Aug 98-Dec98 Had to drop this one cause I moved out of their local call area. $19.95 for Unlimited
3. Iowa Network Services
Linky Dec98-Aug99 For when I lived out in the middle of nowhere. Great connects even in the country! $11.95 for Unlimited if you were a local phone subscriber, which was pretty much everyone who had it.
4. Cable modem. Aug99-Present. First it was TCI@Home, then AT&T@Home, then Medicacom@home, now it's Mediacom Online. I still have the same cable modem, and I'm still getting roughly the same speed. Freakin expensive, but still worth it.
Before then I got on the net via the Univ. of Iowa when I went up to visit friends, or via a then free BBS/half-assed Net gateway called Midwest Access Online that folded 1 week after going from being free to a pay service in Aug of 96. (hmmm I wonder why...)
