Again there is nothing wrong with the Jet (again if it is the redesigned triangular frame) it is as good as any of the other saws in the same class and does have a 5 year warranty where the Grizzly for example has a one year warranty. You see Grizzly in so many shops for primarily one reason, they are inexpensive and thus offer a solid value but there cheaper lines, which is what you generally see, are at the bottom end of the food chain.
What exactly is your budget?
In the 1,000-2,000 range you have basically 3 big players, Grizzly, Rikon and Laguna. In this price range Laguna concentrates on the 14" steel spined saws and while they are excellent saws with many features I really like it sounds like you are looking for a larger saw. With the Rikon redesigns for 2016 I think they have moved into the value lead in the 17-19" budget saws. They redesigned the guides on their more budget offerings, which were their weakness, and now have much better guides than the Grizzly 513/514 series saws. They also offer a 5 year warranty and have good CS. The 10-342 18" saw can be had shipped for about $1450 and sits right in the 513/514 price range. The 10-346 is a big step up from the 513/514 saws and is the most saw for $2000 you can buy, take a look at the difference between it and the top of the 514 range. The value here is Rikon has done a recent update to their bandsaw line where Grizzly has not for 7-8 years (at least in the budget 17-18" range). If you do decide on a 513 avoid the temptation to get the Anniversary edition if your budget allows for more. They are a stripped down version of the 513 to hit a price point and has the worst copy of Euro guides I have seen on a saw in 10+ years and they are a PITA to work with compared to the better guides offered on more expensive saws.
The key to picking the right bandsaw is balancing the budget with your intended use, Grizzly used to be the value leader in the sub-2000 range but Rikon and Laguna have gone a long way to remove that advantage.
