Craftsman has 2 very inexpensive routers, one for $50 and one for $80. The $80 router has the plunging feature as described above and many more features (both new and improved) over the $50 router. I own the $50 version and it's a pain to work with. Changing bits is a real hassle, the fixed base makes successive cuts annoying because I have to stop the router, make all the adjustments, double check if theyre right, turn it on and continue my work, whereas a plunge router would let you do that on the spot, easier and faster.
As for a router table, honestly just make your own. They are very easy to build. Premade router tables are extremely expensive.
To make a router table, all you need is a good piece of plywood (or MDF). Drill a hole out where your router will be. The hole should be only slightly bigger than the largest bit you have (if you make the hole too big, it will just want to **** in smaller work pieces). The router base itself should have some holes drilled through it that you can attach it with. Trace out the holes, drill them, and get then get some bolts so you can attach it to the router table directly.
From there you could build a nice fence for it, cabinet/table, etc, but if you are just looking for a quick setup to do some roundover work or flush trimming (where a fence isn't necessary) then just lay the table across a pair of sawhorses to hold it up.
