For spinning i have a small light two piece rod Berkeley makes called a lightning rod. Casts well and fits in a pack. Think it was $40. For a reel any small inexpensive reel will be about the same. Panther martins, smll meps, nail tails, or tied jigs work well.
Mainly i fly fish. Im partial to a 9 foot st croix mojo trout 4 weight 4 piece rod. Wont cast streamers well but its just the trick for working size 20 dry flies in mountain streams and ponds. A small inexpensive reel and some double taper floating line- its a potent package for under $300 total.
For any large lakes or rivers im partial to an old 2 piece 6 weight with a vintage g loomis reel.
