Chris, to quote yourself:
"Life is too short to drink cheap wine"
Likewise for the digital camera arena, it is unlikely that on your travels you will be faced with the same photographic opportunities ever again, hence take the best equipment to take the best photographs you are capable of.
Currently (2009) in the compact range, film cameras are still better. Regretfully these cameras are not as versatile
You asked specific for cameras:
I agree with the Bridge range, but disagree with their practicality and strength
within your budget and intended purpose on a motorbike. ie it wont last long.
Compact camera wise, I would like to suggest two:
The
Fuji F200, and the
Ricoh GX200 (or 300 when it is launched)
The difference between which of these two to buy, being whether or not you are actually going to learn and understand aperture and shutter speed controls. if you are get the Ricoh, if not the Fuji.
The reasons for my suggestions being great quality images at a budget price.
One of the Canon G range is your other choice, which are higher priced but very good too.
And of course the highly recognised Panasonic LX3 or TZ7
for the super zoom range:
'Compact Super Zoom' Camera Group Test (Q2 2009) Review: 16. Conclusions and ratings: Digital Photography Review
I suppose you should go with the superzoom cameras over the ones I suggested, but I am going for the Ricoh myself once my Fuji E900 has died.
Unfortunately there really isnt a fantastic compact digital camera out there and my ageing Fuji was one of the best and still holds its own.
But most depressingly there isnt a decent digital compact camera with AA batteries on the market at present, that is the travelers bane.
The other choices are the Hasselbald Xpan or Mamiya 7 for the ultimate results
