Macro achromats (Quality vs. Price)

It seems that a decent achromat is an important part of a good image acquisition in the 35mm adapter. It can also be the most expensive part if you use good stuff like Century Optics. I found Raynox DCR-250 for 60 bucks at B&H. Although it is not advertised as an achromat, it is one according to http://home.planet.nl/~heuv0283/achromats.html. It seems like a good alternative to Century Optics, which is $200+. Its also pretty versatile in terms of its mount (clip on). Anyone had any experience with it? Is it even in the same league as Century Optics?
Also, if anybody has experience with other reasonably priced macros, please share.

More on Achromats

Thank for the links Pete. Do you guys know if there is a mathematic formula to figure out minimum focusing distance using different macro lenses? I am using gs250 and its focusing distance is about 16inches. Would +8 macro(Raynox) be enough? Trial and error method can be quite expensive.

I think the idea is stronger is better, but the stronger the macro, the more barreling I believe you get. Go for the C.Optics or something that has a name brand.
