I hate to be the bearer of bad news but afforable and double rifle are two words that don't usually go together . Try Merkel out of Germany. Not cheap by any stretch but still somewhat below Holland and Holland, Westley Richards and Purdy and the like. Cabelas has a fine gun room on line on their web site that sometimes has a nice used double for a decent price but usually even they are priced at or above market value. I've allways wanted a nice double myself but my housepayment usually gets in the way!
Yeah, found the Bakail (or however its spelled). They do have a double, but only in some common US calibers, the biggest (45-70, 30-06, 308, etc.). Nice looking. Might do one for giggles, but not a supplier in big calibers.
There can be too much of a good thing with antler rattling.
I like to hit the horns together for a good 30- to 40-second rattling sequence and then hang them up and resist the urge to hit them again.
This works to the hunter's advantage, because if a buck has heard it, he may have been 300 or 400 yards away and he comes in and he's not exactly sure where it came from.
When finally is time to rattle again throw a slight change-up into the routine.
The second time, don't rattle as loud...
