thank goodness i read this thread ...geez . i have a 8700c but also a 7290 and i was thinking about buying a 7290 from ebay since i completely ruined my 7290 after driving over it !!! i know , i know ... how did u do it ? lol , trust me , i wish i knew . but anyway , i've always been careful when buying from " people " and not stores but i almost did buy from someone on ebay and now i'm thinking twice .... i mean , i pay someone 150.00 bucks for a BB paper-weight ??? i think i'll do without ...
