The Freesat web site has the Grundig at twice the price of the Bush/Goodmans but they're all supposed to be to the same specification and there aren't any details so I don't know why there's any price difference at all:
freesat HD.
Humax is much the most popular name though, so that
would probably be the one to go for.
The price for the Grundig is no doubt the latest RRP rather than being based on actual prices as Harvard no longer market them. You will remember that the name rights reverted to Arcelik in Turkey who market various Grundig branded consumer goods including laptops.
Harvard have now announced they will start to use "Vision 21" as a brand name. Going on their history, that "make" is probably best avoided too although I am not aware of any boxes yet on the market.
The Grundig name rights in the UK now belong to Manhatten who have released freesat boxes under their own name recently. The HD box looks remarkably similar to the Freeview HD box marketed by Harvard since the case used is the same as the Alba and Tesco Technika STBHDH2010 variants and Manhatten's own. In another forum, the company assured me that although the manufacturer was the same, the circuits and more importantly the firmware is completely different. By the looks of things, the box appears to only have the LED on/off status light and no time/channel display. It depends if, like me, this is offputting to you.
The Humax had/has a known problem with a duff batch of capacitors used in the power supply resulting in the "chasing snake" lockup. This usually shows up within the 2 year Humax warranty period and you would get an exchange however the Richer Sounds guarantee is a definite plus if not a must have.
