My nephew set this up for me and it was easier than I expected. Don't be intimidated by the technical stuff — most of it is just clicking Next a bunch of times. If you get stuck, the Help file actually has decent instructions for once.

Whatever you do, don't pay some 'computer guy' $80/hour to do this. It's a 20-minute job you can handle yourself. There are step-by-step guides all over the web with screenshots. Save your money for a faster modem or more RAM.

I posted this exact question on a newsgroup a while back and got a ton of helpful replies. Don't sleep on Usenet — comp.* groups are full of people who actually know what they're talking about, way more than some web forums full of script kiddies.

My advice: don't overthink it. Pick the option that works best for your situation right now. Technology changes every 2-3 years anyway so nothing you choose today is permanent. The best technology is the one you actually use.

I learned the hard way to always back up before messing with this kind of thing. Burn a CD-R of anything important first. It takes 10 minutes and could save you from losing everything if something goes sideways.

I work in IT and see this question a lot. The short answer is yes, it's worth doing. The long answer depends on your specific setup. What operating system are you running? That makes a big difference in the approach.

First thing I'd do is reboot and try again. Sounds dumb but you'd be amazed how many 'tech problems' fix themselves with a restart. If that doesn't work, write down the EXACT error message and search for it — somebody on Experts-Exchange or a Geocities help page has hit the same thing.
