Gotta say, the Modcan stuff is the kind of modular that always makes me want to buy it after I try it out in store. It's labeled clearly and does what it says it does very well. This is in opposition to a lot of contemporary modular which is labeled very obscurely, and don't always do what they say they do beyond a narrow range.
Modcan also seems to be building systems approach modules. Not 'most bang for your buck' one offs like a lot of other brands.
If I had $4k earmarked just for synths I'd look at the aluminum Voyager for a moment, then I'd probably buy a bunch of Modcan (with a few Malekko and Doepfer thrown in).
Macbeth is up there too, but golly gee, $4k doesn't get you much from Macbeth.
