Joseph, In my opinion....
The RAS has some disadvantages that may warrant your consideration.
The over arm that carries the saw/motor has a locking arrangement to set it at common angles such as 90, 60, and 45 degrees. There must be some amount of clearance in order for this mechanism to release so you can change to a new angle setting. Considering the length of the arm only a thousands or so clearance at the lock can equate to a 1/4 inch or more at the end farthest from the locking arrangement. This means cuts that are not true. It also means that for each setup change you must use a square to set this accurately before locking it down and make a few test cuts to be satisfied it is ready for your project, this equates to lost time.
Ripping is no problem as long as it does not exceed the capacity of the blade to post area.
When the RAS was introduced many people lived and died by it, but that has pretty much faded, some still swear by it however but they are few.
I have two RAS's (not that I set out to have them, they just came my way). One I use for rough in type work in deck building etc where precision is not mandatory. The other one I use for cutting scrap wood for the wood burner that heats my shop. On rare occasions if I have a large production job where all 3 table saws and the panel saw are setup for repeat cutting, I'll set up a RAS for one of the less critical cuts.
So.... if you really want one and can buy it at a modest cost they MAY justify the space in the shop they consume. I would think twice before purchasing one new, there are plenty on the used market. I have given one of mine away 3 times but it keeps coming back!
