I plan on getting one of the Mosti Chile Fresco buckets from FVW, having done them a couple times now. I would say Mosti's juice buckets are as good as the high end kits, and even better than those if you add a grape pack. I believe the Total Dissolved Solids (TDS) of these frozen juice buckets is higher than that of the Mosti Alljuice kits.
The juice is balanced and inoculated so all you have to do is bring it to room temperature and its off to the races! I have made the Carmenere (2009) and Cabernet Sauv. (last year). I haven't bottled the Cab yet, but am close to it. The Carmenere was very good, until it was gone! It was easily the best batch I had made before using fresh grapes, and on par with the Red Mt. Cab.
You have options to do MLF and use whatever oak you like, so that's somewhat liberating. You just need patience, since it will benefit from aging like fresh grapes.
