Which Receiver-Drier?

[Phalcon51]

I need to replace the receiver-drier in my '86 300E and I see that there are generally 2 available: one made by Fligor for about $42 and another made by ACM:Germany for about $70.00. Is there a practical difference between the two? Am I getting more drying capacity with the more expensive one, or is it just all that extra shipping expense to get it here from Germany?

Opinions eagerly awaited.

Thanks,

Gary
