My $0.02 ...
The biggest bang for your buck at the moment is probably a conical burr grinder if you don't already have one. I recently had all of my Christmases come at once. I had left my own super jolly at work and it went missing. Until we figure out what happened to it, I'm borrowing a Kony. Oddly, it doesn't seem to be displaying its characteristic increased acidity as much as it does at work, but there is no doubt that my shots are blonding later and are doing a better job of maintaining colour and flow-rate throughout. There is also more crema, which is nice, but not something that I care about greatly. The plot thickened further when I turned up to work and the usual random assortment of majors/k10s/bnz conicals that we swap around had been replaced with ...

Contrary to what Jim thought in "Can it beat the Robur," I thought that there was a pretty big difference between the robur and the other grinders that we had had, including the other commercial conicals. This might well just be the ease of use factor, which Jim wasn't testing for. The shots were simply easy to dial in, thick in mouthfeel, rich in crema and clear in flavour. However, I should note that when we first put the Roburs on the bench there was a slight bitter twang to the shots. We fixed that by running a few kilos of coffee through each. Frankly, the difference isn't simply a matter of taste - you can
see it just by looking at the pours or even looking at the espresso in the cup. Needless to say that I really hope that the Roburs stay and that I would definitely drop the coin on a Robur before a GS3 ... even if it meant cutting the bottom out of my kitchen cupboards to accommodate it!
As for the GS/3 and Brewtus, I have only had a brief play with each and in 240V. I worked on the Cyncra for a year or so. I wasn't particularly impressed with the Brewtus; so much so that I bought a HX instead. For all that I know, the 110V machine might be a different beast and I'd certainly be interested to fool around with the Brewtus again. The Cyncra and the GS/3 are pretty close, but I get the inkling that the GS/3 might actually be capable of better shots. I would need to use it for a lot longer to be sure and I would be happy to do so if someone had one spare ;P Based on my experience, I'm pretty sure that your average HB reader would be able to pick the difference. However, whether or not it is worth the coin is a different question. As I said, I think that at this point your typical HB reader would be well advised to buy a robur or similar first. If you're talking about what's in the cup and you're spending 1/2hr to 1hr per day making coffee, I think that you would probably be very happy to have a GS/3 or a Cyncra sitting around. I would certainly love to have a GS/3 at home. But I acknowledge that neither is really a perfect machine; for starters, neither has a drip tray that is as good as I would like, nor does either really have that great a fit and finish (although I haven't really taken a close look at the latest Synessos). The GS/3 has the paddle group in the works and for all I know there might be a few more tweaks down the line. The sensible thing to do if you're interested in these machines would probably be to put the pennies towards a Robur and wait until the paddle group is released. All of this presumes that you are interested in a machine that produces clarity of flavour and will really allow you to tweak your shots, at the expense of giving poor beans nowhere to hide. If you prefer to have more margin for error, heavy mouthfeel and more generic chocolatey flavours as opposed to clearly defined origin characteristics, you're probably better off with an e61 head with a long preinfusion time.
Hope that's of interest,
Luca
