Ok Gents... I can help you tip the balance:
CALC (Club La Ceiba) two 91 FX (and an OS 120 Surpass II) never were able to run reliably for their three "sequential" owner.. you now the "you are doing it wrong, give it to me I'll fix it" types..gave up on 'em

Tegus (Club Tegucigalpa) at least 5 to 8 91FX's are being used for several uses at the club.. from very expensive paperweights to door holders.. (last comment I heard WE hATe'em just Hate'em...)

Well.. here in HOnduras there aren't many modellers, but the 50 or so active would rather be using rubber bands for power than an OS 91 fx.
