Where to find these Beatles Albums?

I am looking for the folowing Beatles albums

1) Rubber Soul
2) Revolver

in the MONO MIX! I am interested in either CD or vinyl format. Thanks all, in advance.
There are some for sale on Ebay.
Check amazon also.
I just received a gift today that another Audiogoner ordered through Acoustic Sounds. While thumbing through their catalog I saw they had the entire Beatles collection available as new pressings with many of them being mono. Unfortunately I left the catalog at a friends house for him to look at. I'd check this out.
