Haven't seen the ad and dont know how much they are asking for it. What I can tell you is Hudl are releasing a newer version on October 9th.
I wouldn't bother rushing to buy it if it's the older version, they are more than likely dumping the old stock at knock down prices. The new one is likely to be one of the best budget talets around.

If I were you I would wait another month as it will be tablet wonderland then.
Everyone will be releasing their new versions for xmas and there will be bargains galore to be had.
I cant remember the exact specifications but many of these tablets are cheap "no name" Chinese imports. If it goes wrong you are never likely to get a replacement.
Go for a brand you can trust like Tesco with the Hudl, or an Amazon Fire, or a Google Nexus.
Well, yes I have purchased Samsung Tab2 last year and I would say it worth every single penny. I would say just loved it helps me connecting with out clients over Skype, also gives me access to sometimes create docs on to the go, I do find it useful to manage my pictures,watching movies and......I would just say with everything ! So, I would advise you to move forward with it !
