You need to define "non-expensive". Budget kayaks will start around $300 but have a limited weight capacity. A rule of thumb is to not load more than 70% of the stated weight capacity (your weight plus seat plus all gear). Factor in a good paddle and PFD. How will you transport it? How will you store it? Sit-on-top or sit-inside preferred?
Check the kayaks for sale here, on craigslist, and Texas kayaking web sites.
