"Worth it" is really hard to determine for other people. I got mine just a few weeks ago from Woot for $249 + tax & shipping. As B. Diddy noted, Woot has at least one tablet deal a week. Another place to look for deals is Gizmodo's daily 'dealzmodo' article.
But back to "worth it" ... you have to decide what you really want a tablet for. True HD for watching movies/tv shows was my primary purpose, so I don't really even need to overclock or flash a custom ROM. If you have specific graphics/gaming requirements, you might want to look elsewhere. The screen is really nice, but touch-sensitivity (lack thereof) is starting to bug me. I put an anti-glare protector on, but I don't think that's the only reason that I sometimes feel like I'm pounding on the thing. I bought a cheap stylus, but that hasn't helped. My last major gripe is that the device, for all practical purposes, does not charge over USB. Only the stock charger will charge it up and there is not a mobile charger that supplies the 12V required. Replacement A/C chargers also appear to be pretty hard to come by, so I hope mine doesn't die.
Everything else meets my expectations, but if I had more time (I wanted this tablet in time for a vacation I'm taking soon) I might have waited for the new Nexus 10.
