You'll be happier with glass, get as big as you can, the longer the boat the better they handle rough water. If you plan of fishing every week in Texas you will be fishing rough water. A 19' or 20' boat with a max HP rated motor if at all possible. If your looking used (I would suggest that for a first time boat owner) wait a few months used boats are premium priced right now but will drop off in November. If you go used be sure and have someone reputable check it out for you. Be patient and don't jump at the first one you see (ask me how I Know). Good Luck and remember B.O.A.T. stands for Break Out Another Thousand, just the way it is.
