Refinancing First Mortgage & New Larger HELOC?

Hi, My current residence has a first mortgage of $197,000 and a HELOC of $21,600. Are lenders willing to refinance first mortage of $197,000? and also take out a larger HELOC? The property has approximately $80,000 in additional equity. I don't want my mortgage payments to be higher then they are now, would prefer a larger HELOC amount. I heard that it's harder to refinance first mortgages when you have a HELOC as well. Usually people combine then but in this case I would not want to combine them. Thank You [addsig]
