This question has been asked 1 or 2 thousand times in the last few years
Not sure what your definition of not very expensive is but I would keep an eye on the OFC ads some good deal pop up every oncee in the while, barring that if you can wait BPS has some good deals when the big spring sale is on i.e last year a picked up a JM signature reel for under 90 bucks and imho it is every bit as good as a Curado.
Oh and by the way a good reel will not turn a bad caster into a good caster
