Any good merchant clans?

Hey I have 20m on my pure and im looking to invest it so I can get a set of D claws, basically I was wondering if you guys could answer some questions.

What merch clan have you guys merched with?
Are you able to get a rank?
Did you reach close to or over your dump price?
How long ago did they get their new item?
Was the merch clan active (talking and such)?
How long has this merch clan operated for?

Thanks I need to invest this quickly
