For one thing, the anti envelope was never made. And also, make sure you really read up on some of these modules and their issues.
Above all listen to demos. There's a lot of variety in every module, some geared towards dirty sounds, some pristine, some intentionally chaotic that embrace analog flaws whether good or bad, etc.
The 'one manufacturer per row' thing is nice to look at, but you end up limited yourself with choices based solely on hp. If anything, pick 2 decent companies and do 2 rows each. I'm a huge fan of Intellijel and it covers most of my system, but I still space stuff out to be more convenient instead visually aesthetically pleasing.
