36c3: GSM base stations wanted

Dear all, 36c3 is going to happen soon, and as usually we're planing to setup our own GSM/UMTS network (LTE is to be discussed). While we do have enough UMTS NodeB units, we're looking for heroes who could sacrifice their GSM base stations (preferably sysmoBTS or nanoBTS) for the duration of the congress. Note that we're not considering SDRs (unless somebody with a strong aspiration wants to ensure proper clock distribution, filtering, power amplification, etc). Please let us know 1) how many (and what kind of) units we could borrow from you, 2) can you bring them to Leipzig before the first day, or can you drop them somewhere in Berlin (Sysmocom? AfRa?). Thanks! On behalf of the GSM team, Vadim Yanitskiy.
