Carp fishing can be as cheap or expensive as you want to make it. There is a shed load of very good gear out there for not a lot of money, when i started carp fishing 35years ago there was very little choice. There are some things its not worth buying cheap.. or you will be buying again
So i would go for second hand gear rods Fox Warriors in 12ft 2.75TC will be soft under the tip and put a 3oz lead a 100yards, can be picked up for £35 a rod.
Reels Shimano baitrunners 6 series and 8 series again £35 a reel, line bulk spools of Daiwa Sensor or Gardner Pro in 12 or 15lb is £10.
