JeanM - that's not an easy question to answer, there's quite a lot to consider.
You need to think about the potential benefits of broadband, such as speed, convenience, ability to phone while surfing, no time/bandwidth restrictions - against the disadvantages, such as increased cost (which may not in fact be the case), increased threat of being always online, and the variable performance due to contention ratios.
In my case, I was using 128K ISDN about 2-3 years ago, before flat-rate came along, so I was paying for the cost of the calls. This was just about fast enough for me, but of course I'd have to drop down to 64K to use the phone at the same time. It was also quite pricey - I work at home so use the Internet a lot, and when flat rate came along, I jumped at the chance. However this was only available at 64K - I guess 128K is now available, but I haven't checked this out recently. ISDN 64K is fine for browsing, but too slow for large file transfers, which I need to do quite often.
Also, when the ISPs started scaling the flat rate according to how many hours per week you used online, broadband actually became more cost effective for me. BTW I use the Home Surf option from PlusNet, which at £18.99 p.m. is great value, but some evenings the speed does drop off considerably, well below what 128K ISDN can do. But I'm mostly online during office hours, where the performance is usually fine, and I wouldn't go back to ISDN, *unless* they start to introduce time or bandwidth restrictions, which I can see happening before too long. Even then, I would probably just pay the extra for a better level of service, such as 10:1 contention or whatever.
We all have different needs and circumstances - try to work out what all the pros and cons are for you.
