Wanted: Larger screen Sat-Nav

[HappyH]

Got a navigo VII with a 3.5" screen at the moment & it's great but due to a combination of factors (mainly me old eyesight ain't what it was :Frog I need a larger screen sat nav if anyone's got any recommendations. Think 5" would be my preferred option, had a look at my mate's 4.3" Garmin Nuvi & while it was obviously easier to view than mine I think the 5" would be better. 7" & larger just tooooooo big imho.
Saw some on ebay for around 50 quid from China but would prefer if anybody's got personal experience of one they'd recommend. Must be hackable so I can put my choice of maps on there.
Cheers in advance,
HH.

Had a look thru some old threads on here, think Captin suggested a Chinese one from pandawill, maybe go for one of them. Not in a dreadful rush so I'll have another look around.
