IMO I find a table saw to be my most necessary tool in that I do not use any dimensional lumber for benchwork except for glue blocks & legs. All support elements are slit lengths of better plywood. Much more stable, less prone to warpage, very strong.
Chop saws are very helpful, but if only one tool is in the budget, IMO it is the table saw. You can not rip with a chop. Almost everything you do with a chop saw can be done with a table saw. Can not go wrong with Ridgid products IMO.
With either a chop or table saw I would recommend at least a 10" blade. 8" blades are too restrictive for benchwork. 12" blades for both are best but the price and size can be a deal breaker for many. Opt for the laser option for your chop.
IMO, just use little tools for little models.
Also, with proper registration, most Ridgid tools have a lifetime warranty. Yes even the batteries have a lifetime warranty. tt
