How close do you want to stay to that budget? Like 130-160 close?
If you want to stay right at 100 dollars then your best best is to go with the Bass Pro, Pro Qualifier. Dual breaking system, smooth, well built and has a proven track record of lasting.
Right now Bass Pro has the Pro Qualifier combo on sale for 99 dollars. Rod and reel. The rod is ok, much better than what your probably using, but will do just about anything you need it to.
Plus bass pro has a coupon code VISIT20GC. 20 dollar gift card for 100 dollars spent online. Have it shipped to your local BP and it's free. Take that 20 dollars and get some line.
There are some great other set ups out there, but that by far with the sale and code has got to be the best out there right now.
