DFRduino GPS shield ±/feedbacks?

Hello,

I'm looking for u-blox5-based GPS module. Got one faulty from sparkfun (http://www.sparkfun.com/products/9566) - learn my lesson.

Now, I have also found one made by DFRduino (http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=160641958128&ssPageName=ADME:X:RTQ:US:1123) - its $5 more expensive, but is embedded onto the shield.

Any happy/unhappy users of this shield - please respond!

Thanks!
