I use MX,
it's been fine since I bought it - over a year ago I think. I'm just building and maintaining a fairly simple website - nothing clever, so it might well be that iI've been lucky enough not to use anything that has problems associated. Having said that I tried a few programs enroute and I find Dreamweaver much the easiest to build the site with - using MX my site tends to come out looking the way I expect it to, which with other programs often wasn't the case. (I absolutely tore my hair out with Front Page, for example)...
Trial version is okay and worth taking a shot with (I think it's quite often on the cover of PC mags, notably those that are devoted to building sites) .. that's how I came to buy it myself - liked what I managed to create using the trial, and stumped up the cash rather than go back to life without it.
