After a lot of research I narrowed it down to the gaggia mdf and the rocky. I bought the MDF because Peet's had it on sale for $199 which was a great deal. I paired it with the Gaggia Classic and have been very happy with the performance of this workhorse of a grinder. Usually have it set between 5 - 7 for espresso depending on the beans. Once dialed in it's quite consistent and produces great results. The doser does help reduce the clumping when you're filling the portafilter compared to a doserless grinder.
Some improvements I'd suggest is a sturdier doser lever, make it stepless, and Add some rubber feet on the bottom so it would be more stable. Actually you can modify the grinder to make it stepless and add rubber feet on the bottom but it would be nice if it came out of the box with these attributes.
Overall a good entry level espresso grinder for the home that should satisfy your espresso needs.
Bought the MDF from Peet's coffee and was very pleased with their service. Shipped promptly an have had no problems with the grinder thus far.
