I have just finished building a four language (qTranslate) realestate site with:
a) Realestate search
b) Realestate section in the /wp-admin/
c) Customfield drop-downs for type of property and type of offer
d) Customfields for price
e) Search for price between range etc.
f) Main thumbnail for each offer + additional galleries generated in-post (no nextgen)
I have to say - Custompress saved a whole bunch of time - love it.
Thank you WPMU.
