DF54 Series
Great value for espresso, but clogs and poor for pour-over.

I think you might like the NB64V, which is available for <€400 on frekko.nl . Haven't experienced any issues over the first months of owning it; no clumping, no static, very little retention, nice materials, acceptable noise level. I upgraded from a J-Max, also because of the knob, and have been very happy with the coffee it makes (granted, my preferences had already shifted to lighter roasts before switching, so the J-Max was already not ideal)
Have a look at the espressa Orbit 64 - this is the one I got when deciding between DF54 and the Shardor grinder. Just got it last week from Coffee Plus
Wow, I never knew Shardor type flat burr grinders are available in India. Go for Cipher Rift. I have a g5, there is no static. Retention barely there. No complains about the taste or quality. I would still suggest you go for Rift for flat burrs
Technically, flat burr over conical grinder any given day. Better particle uniformity, less fines. While it does make a difference brewing espresso (for me), it isn't a paradigm shift. I would go with Cipher if I was buying.
I do Aeropress, Clever Dripper, and drip brewer. I replaced Encore with a Shardor 64 running Ode2 burrs. Encore produced a lot of fines. Have the K6, use it for lighter roasts. Non offense, but any option will give you remarkably better results than blade grinder.
Running Shardor 64 w/ Ode2 burrs. Very pleased with the result.
Same manufacturer and same factory but this one with titanium burrs is really much better and an all steel construction. Quite strong and I could gush for days about its consistency and fluffiness.
