Which model did you decide on and how’s it working out for you?
I would think how often you plan on using it, location and what type of varmint you’re going after, might come into play in what type caller you decide on. If you get out 30 times or more a year you may want to invest in a good caller and that means several hundred dollars, like $500/$600.00 when everything is said and done.
If you need volume due to wind or long range then there’s a couple on the high end that would do you a fine job, namely the FoxPro CS-24 and the Wildlife Technologies MA-21. FoxPro is heavy into marketing their fine products while WT goes by word of mouth mainly.
If you don’t need big volume and are only going to use the unit “occasionally” over a year, then just about any unit out there will probably do and Fox Pro has several models to choose from and they have been around for awhile now and have decent CS. Go on some varmint sites and there are plenty of smaller units for sale at a good price.
Myself, I have the MA-21 (because they have been around longer and had the best sounds in the business for many years plus the range on their remote is the very best in the business today) and it’s all I’ll ever need for the rest of my days. I started out with a Herter’s record player back in the late 50’s or very early 60’s and then moved up to the tapes etc. – the high-end callers today are just amazing and when you look at some of the bells & whistles on a remote, such as those FoxPro has, you may think you’ll have to go back to school.
