That's cool, nice to know what to buy for less demanding clients on a budget. Where quality and reliability is still a concern, but you want to ensure they are getting a great value.
I'd really like to see some nice midrange PSUs compared-modular only. Why? Because modders/enthusiasts can mod the cables without voiding the warranty.
More recently, (say over the last year) many fully modular power supplies have come to market for just this reason. This includes non-modular stalwarts like Corsair. This meets a lot of folks needs in regards to cable management, visual flair, and cool, quiet computing.
Of course this could lead to quite an array of units, so perhaps one could break it down to 500-650 W comparison, followed by 700-850W, then the big boys for those monster builds we all dream about.
