My Premium 360 died, just in time for Christmas, so I was looking for an Arcade / Core system to tide me over (I have the hard drive from the original machine).
Was in my local Blockbuster last night and they have the Arcade console pack with the 5 arcade games, plus Halo 3, FIFA 08 and a choice of either Assassins Creed or Kane & Lynch for a total of £229.99 which I thought was a good deal considering you'd be very unlikely to find any of those games for less than £25 each.
My shop had FIFA out of stock, which suited me as I already have it but they provided a list of other options which included Bioshock, PGR4, MOH Airborne and many others. I went for Tiger Woods 08 as I already had most of the good ones on the list.
They did have several other bundle options including the Pro and Elite consoles but I didn't really examine those closely given that I was only after the Arcade version. I think the Pro pack with the same games options was £30 more although they did have quite a lot of options with various games packages.
There was also the option to add the Forza / Pinata and extra wireless controller pack for an extra £20.
