How much is "a little money"? What does a zink call average?
A cheap Zink duck call "Power Hen" in the Poly material will run about $25 dollars. Then the calls go up from there to the Money Makers which run about $150. I would go to a sports shop and try a few. Some of the Zinks take a higher volume of air and if you don't practice a lot you can be winded and cut your notes short scaring the birds. I have several Zink calls and found that I liked the Tim Grounds Triple Crown goose call. I also use a RNT duck call. A cheap duck call that is over looked is the Primos Original Wench call. The birds respond well to it, but I tune it frequently. Also check out the Duck Commander ones. They may not sound like some of the calling tapes but the birds respond to them well. That's the ticket, your not trying to do a calling competition, just good response from the birds.
