I took a new-to-cycling friend to my local lbs last week intending to buy a 7000. The lbs doesn't stock them but said they could easily get one. They said the reason they don't stock them is because, compared to the rest of the 7X00 lineup the 7000 has lower quality components - more akin to what you'd get at Walmart then a bike shop. The price of the 7000 was $259 and the 7100 was $309. When the lbs offered us the 7100 for $280 we took it.
Incidentally, this lbs offers free lifetime adjustments on any bike they sell - but they feel the lower end bikes end up spending more time in the shop than on the road. Who knows how accurate this info really is but I thought I'd share.
