First, I had no idea it had flat wheels/tires. Gotta be the only small Asian saw without them.
Again, I think you will find the Rikon and the Laguna both as a step up. The Rikon is cheaper and that deserves consideration.
I prefer the Laguna guides, the 10-326 did address the difficult to adjust guides from the 10-325 which were horrible to adjust and now use bigger bearings and are toolless. Not a huge fan of off the shelf bearings used for bandsaw guides (including the small Carter guides). I also don't like guides that run perpendicular to the blade as it sets the bearing point higher and the bigger the bearing the higher this point gets so the blade isn't supported as close to the cut. I won't go into Euro guides since it is beyond the scop here. The Laguna guides are tooless and easy to adjust. They are particularly easy since they can be run just touching the blade, which is the way they are designed to run but you will see varying opinions on setup. Run them just kissing the blade and they will provide the most support. They provide support of the blade at multiple points including close to the stock. I prefer solid block guides to bearings and ceramic to any other material and the Laguna version to all others. That said I have multiple types of guides and don't feel the need to replace them all with Laguna guides. Be aware the occasional spark that comes off ceramic guides freaks some people out.
I like the Laguna better, mainly for the guides beyond that it is more or less a toss-up for me. The Rikon does have a 5 year warranty if that motivates you. I don't think you will be disappointed with either.
Of all the laws Brandolini's may be the most universally true.
Deep thought for the day:
Your bandsaw weighs more when you leave the spring compressed instead of relieving the tension.
