I also have the Catana / Sienna combo (7 foot 2-4kg rod, 2500 reel) 4lb braid, 6lb FC leader and it has served me very well. This outfit casts very light plastics with ease and will handle decent bream and flathead no probs. If you shop around you can pick it up for well under $100 which will leave you some change to get a few plastics/jig heads and maybe even some hards.
Good luck with your purchase.
