Funny you should ask! We just moved into a house a few months ago, and it has a pool - we weren't looking for one, but liked the house, so here we are! We've survived our first summer - at least the last few months of it, anyway. The pool is older (20+ yrs), but most of the replacement work had been done before we bought the house, so we were lucky in that sense. It's an in-the-ground sand base with vinyl liner (not sure if this makes sense, that's how the owner described it to us) The liner and pump are brand new - he said that he paid a few thousand for both, if that gives you any idea of possible costs. We live in a four season area, so the pool is usable from about May to late Sept. The electric to run the filter didn't run more than $15 extra per month (estimated). Chemicals, we buy in bulk from Costo, Sams, or wherever there's a sale.
The work involved wasn't as bad as we expected, but it is constant maintenence. We weren't sure about hiring a service - it was later in the season and most of them were already booked, so we figured we'd go the DIY route. It's been about 15 minutes a day, every day: skimming, water testing, chemicals and checking the filters. Every 4 days, there's an extra round of chemicals and vacuuming (additional 20 minutes). We usually did it while the kids were swimming, so we were going to have to be out there anyway (our children are all under 4). We're in the process of closing the pool, now, and it's a huge learning experience. Not brain surgery, but definitely lots of stuff to remember for next time! And we did have to get someone to keep up with it all while we were out of town (luckily we have neighbors who were willing to work for beer and pool priveleges

)
While I am NOT a 'pool person' (hate cold, not a big swimmer, etc) I have to say, we have loved having it this summer. The kids are doing MUCH better at swimming and never got tired of going in the pool. It's good exercise and gave us some built-in family time every evening after work. There's nothing like dinner on the grill, eaten pool-side

And that's not even counting the fun 'happy hours' with our friends and neighbors and a few 'cold beverages'
We're already looking forward to next year, when we'll have a full season and will be able to do a few renovations to the decking/pool deck to make it look better and more comfortable...
Bottom line (IMHO) if you get the enjoyment out of it, it's worth it, but it is a lot of responsibility. Once you get used to it, it's probably not that big of a deal. We're still in the learning curve: all the chemicals, tools, mechanics, etc. so it seems like a lot. I'm sure next season will be much easier.
Good luck! I hope you have a lot of fun!
