Calypso phone with RX filters removed

Hi List, Could anyone suggest me where to buy a C155 with RX filters removed? My soldering skills are not that great so I am trying to avoid buying the filter replacement kit from here http://shop.sysmocom.de/products/osmocombb-filter-kit and doing it myself. It seems from the mailing list (http://comments.gmane.org/gmane.comp.mobile.osmocom.baseband.devel/1840) that you could buy it from shop.sysmocom.de, but not anymore?
