Assuming you’re asking about E-callers… I’d suggest Foxpro. A lot of people like lucky duck as well I don’t personally have any experience with LD. As for model we would need to know your budget to help there.
I've been around the Foxpro X24 and Lucky Duck Super Revolt a lot. The Lucky Duck Roughneck a little and the Icotech Outlaw a little. The FP and both LD's are pretty solid. I was not a fan of the Icotech. It sounded like garbage. Probably that specific call but it's the only one I've personally been around.
With your budget I would look at the X24 or the Roughneck. It's hard to say one is better than another. There are a few guys that kill a lot of coyotes by me and some use the LD and some use the FP.
If lots of guys in your area use the FP get the LD or vice versa.
