The back looks like a good deal to me.

I just got the front one, and it is good for what I want, but if you are looking for something big enough to hold a real trunk bag or panniers, or something else of that size, it would be too small.

I also bought the Nashbar bag to go with it from Nashbar (not received yet) and I basically bought the rack and bag instead of a handlebar bag... and for that purpose, it will do me well. For anything more demanding, it may be undersized. I will let you know once I receive the bag.

That is the Nashbar rack I have seen mentioned somewhere else, and it is a mini rack, not full sized. Which is good, as long as you realize it.
