The Thunder Jets I've been in are also cheap boats. They look nice outside, but that's about it, same with jetcraft and hewescraft. NW Jet, Duckworth/Weldcraft, are good options. I love my 18' weldcraft with the outback bracket. It's a 4-stroke outboard, so that means I can't go in too shallow of water, 1 foot or so on plane, but I get twice the mileage. It's also easier to add a link to my kicker to steer it from the steering wheel.
It took me a good year to research and test drive boats until I found one that fits me. good luck.
