I have used PhotoSupreme aka IDIMager. Its actually very good, but more complex than ACDSEE. The problem with ACDSee is that it doesn't see IQ files! But does see everything else, can be catalogued, or just browser. It has crashed and they always have an upgrade version to buy to remedy the crashes each year! Otherwise very good. The non-develop version is rather priced well and maybe your answer.
I just wish the interface could have custom colors as I get it confused with LR or others with dark/black GUInterface.
I was very resistant to LR, and it still has issues,(no PDF, PNG). It also is sluggish. Its dual screen support is limited. The interface and tools are not modular....
but I must say with about 150K images in each catalog, it is still usable, yet sometimes clunky. I wish the sliders bars were easier to grad(I know the other options).
I swap around depending on my need..between ACDSee, LR, or Windows Explorer(which has been rather nice since Windows7)
