So I have been lurking this forum for the last couple weeks as I am in the process of buying a pair of bikes for my girlfriend and myself. I am hopefully going to be getting a pair of Kona Dew Drops for both of us (not sure about me though since my LBS say's I should be on a 58cm but theres none left in Canada! He is checking to see if he can get me one from the states). Decided on this bike because it seems to be a bike that will be good for all the things I want it for (commuting, groceries, being able to go on trails and also want to be able to tour on it) while still being in my price range.

I have been looking for racks and bags online to try and keep the cost down as much as possible since the 2 bikes will be taking almost all my budget. I was just wondering if anyone knows whether these ones I found on ebay are any good (no brand mentioned so can't look up reviews)

Rear Rack (says heavy duty, to me looks heavy duty, but is it??)

Panniers (like the large size, want to be able to do good sized grocery trips and I figure would be good for touring)

Rack Bag

All are from the same seller which would be nice to cut down on shipping costs.

Thanks for any help!
