I personally learned on a quantum, now I prefer the abu-garcia Revo series mainly because of how low profile they are, reel fits well in my hand and its not a chore to cast it for long periods of time. Easy to get parts. I do usually change out the crank for a larger one. I have 4 and have the new revo ike pre-ordered and should get it late September. The cheaper abu max series(black and silver max) looks like plastic junk but basically the same reel as revo but made with cheaper parts. I would avoid those and try to find an older generation Revo for around $100 instead of buying a max.
But everyone is different, you may prefer shimano curado or something else.
They have some plastic parts but Lews and KastKing make some cheap combos with high ratio reels that would be good for topwater. One is called a speed spool, the other Speed Demon. I've casted the Lews version and liked the big crank on it. These are probably good choices to learn with.
I was in D'sSG with my wife and youngest kid the other day getting school shoes and naturally spent most of my time in outdoors section, I saw an "okuna stratus" that looked well made for 50% off($30), there still may be some left. I probably would of bought one if I didn't fear the wife's side eye. I'm a fishing gear and especially lure junkie, I got an addiction
That new company "13" makes some good-looking stuff, "concept" series. No idea if it works well though
Some advice for learning a baitcaster, if you are right-handed get a reel with crank on left side. Wish I could go back in time and do that(not sure quantum even offered it back then). Also, learn with good mono(trilene red box, "smooth casting"), not braid or powerpro. Backlashes are a b!tch with braids and small spectra. Get 14-20lb test, something big and easy to grab when you are picking out backlashes. Mono wont fray like pp if you have to use needlenose or a hook to pick out a backlash. Once you do learn, I definitely recommend power pro but with about 50 cranks of some mono on the reel first as backing, the PP will lay on reel better with the mono backing, increasing cast distance. Oh and make sure you don't overfill the reel with line.
