I would look at the TFO professional series, A Gillies guide reel will sufice.
The kits dont usually have the running line and backing that is required for salt.
Braid backing is better for salt water, a good intermediate running line will cost from $70 and up.
I would get a 6 or 7 wt (I use a 6) if your only interested in estuary bread and butter fish.
35 pnd spectra backing with SA bass striper or bone fish running line are both great for our estuaries.
good luck
