Refinance options for 6-plex with great income in Colorado

We have a 6-plex in Colorado that generates about $70,000 per year in income. It appraised at a surprisingly low $345,000 and our existing bank is offering us horrible terms to refinance. We owe $270,000 or so about 78% LTV. The income/expenses pay the bills handily but we are being raked over the coals (IMHO).

Can anybody recommend a good Colorado funding source that will take our income/expenses into account and give us a decent loan?

Thanks for any help anybody can throw our way.
