You'll need a pretty big router table to run sheets of plywood thru. You could ask the guys at the lumber yard to rip it up for you before you take it home, this may cost you a few bucks, but if money is tight right now its the cheaper way to go. I would always recommend you buy the most expensive tool you can afford, and that's not some stupid joke... Get the best of what you want and you won't spend too much time wishing you had bought a quality tool, a $125 saw really is better than a $75 saw, that's just the way it is. If you make it your priority when you start, you'll still have some nice tools 10, 20, 30 yrs. down the road.
