New Broadmoor runs around $4096 +tax. You can usually pick one up around fair time for about $400-$500 less and finance it through Simplicity for $0 interest (must make minimum payments to avoid all interest charges).
135 hours is a lot of hours. I would be interested in who did the maintenance (owner or dealer), was it done properly, what year is it, what engine is in it (Briggs Vanguard or Intek) and what's the overall condition? The Vanguard is a good engine, Intek has planned obsolescence built in (plastic governor gear inside engine).
I would find out the model and year and call a local dealer and ask his opinion.
