I have the Ridgid 4512, essentially the same as the 4513. I bought it with a 20% HF coupon. If your HD will accept one that may be your best bet. I hven't seen that $299 price point in a long time, maybe not since the 4513 was introduced.
Keep in mind a few things; The 4512 can't do an 8" dado stack, might be a significant thing for cabinetry, You need to make sure you get as little vibration as possible on the table, finding a good spot on the floor and leveling the feet to that spot and then marking the floor is what I did to help. The fence stays pretty square and parallel to the blade but you still want to check it every few cuts as it can and will move if you hit a knot or bump it . Accessories for the 4512 should fit it as a whole, one of the things I found is the zero clearance inserts available are too expensive for how poorly they fit it, might want to make a few out of ply for yourself. Buy a good blade, the one it comes with is only ok for general stuff, framing, not what you need for cabinetry. You may find the built in tape measure is off slightly as I think it measures from the blade center, you will want to make sure you measure from the edge of the carbide tooth to the fence.
