I bought a pair of spanish made bosch snail horns for Rs 1300 about 5 years ago, still sound good, but I wired them to the original wiring I had in my car (VW) - which makes them sound very soft not annoying like screaming saying GET OUT OF MY WAY - they more sound like - excuse me please..
Prices mustve increased by now - Elephant brand snail horns are very very good quality too (OE for Honda), long lasting, but the best Euro sound are from original Italian snail FIAMM horns
