My rear shocks are leaking (oil residue all around the shock tube) so I am assuming it is time to replace them.

What are people recommending?  I am more interested in quality over cheap but a good deal is nice to find.  And for what it's worth I put a set of Bilstein's on a previous van and I didn't think there was much difference from the stock Boge.  I wouldn't rule out getting them again, but what do you recommend. I drive highway and dirt roads in a 2wd Westy.

BusDepot sell a "Premium Boge" $90 (European sourced) Anyone tried these, are they worth the money?  They cost about the same as Bilsteins.   Other suggestions?

Here are some that GoWesty sells.  I thought Meyle was a good brand and these are pretty cheap if they are as good as the OEMs.  They are only $29
