mc4 is the same as the m4d, without the digital timer and the portafilter holder. therefore, you've to hold on to your portafilter while grinding. while you can still use it for espresso, the mc4 wasn't designed for this purpose.
IMO, a doser is a very good espresso making tool in a home setting. macap's dosers actually sweeps quite cleanly at stock.
if you read patryn33's link, you'll know clumping is a problem for doserless grinders, but there's always WDT to save the day.
if you prefer doserless, I highly recommend the vario, which is exactly built for this purpose. although with the vario, I would also recommend you use it as an espresso-only grinder. if you mess with the settings too much, the plastic catch would start to give.
at the entry level machines, between the gaggia and the Silvia, I would take whichever's cheaper and save the money for future upgrades.
they will be challenging to pull good shots from, even more so for beginners. which led to many giving up. that's why many seasoned users urge beginners to save up and get a proper one instead, at least one with some sort of preinfusion.
I'm all for it to get your stuffs from overseas, esp the grinder. grinders are usually built to last a lifetime and the savings makes it worthwhile to take the risk.
to give you an example of how much is the savings:
the Mahlkonig K30 Vario.
from Chris Coffee, including shipping, a little less than $2440sgd, excluding gst.
I was quoted $3.6k sgd from a local distributor, excluding gst.
yes, 110v I know but you get my point. you can still slap in an external transformer for $200 and still have huge savings.
