I'm still using my now decade old Rockler brand table. I changed the plate out when I put in a larger router for the table only. I suggest you make your own, buy a plate that's pre drilled for the 1617. Find a source of real Baltic Birch ply and use it to make a top. Make it 3 ft long by about 24 inches wide. Lay the plate on that board and draw the outline. Then use a jig saw to carefully cut it out.
Kreg makes some leveling screws that you put in the corners of the cut out opening. See the picture below. You will then use the screws in the Kreg levelers to make the plate absolutely level with the Baltic Birch. If you can feel an edge with your fingernail, it's not quite flat.
As far as plates go, I prefer aluminum, pre drilled for the Bosch fixed base, and with twist lock type inserts. The pix below is of the plate I used and you can see the inserts are red. Some plates come with 3 holes to hold in the insert, but those screws instantly disappear.
The same small bolts that hold the round base on the router are sometimes used with the plate. but if you need longer bolds, you can find them in the odd piece drawers at Lowes and sometimes Home Depot. Pre drilled plates will let you use the Bosch provided bolts. They don't have nuts but thread into the fixed base of the router.
The fixed base is bolted directly to the plate. You can look for and find a Bosch part that is a "key" that allows you to do final adjustments on bit height.
You will need a fence. A really really straight piece of 2x lumber will do, or you can buy a commercial fence, most of which will a small dust port and have a variable split fence so you can open it to fit the bit. A couple of clamps from Harbor Freight $4-5 bucks each, will hold it in place as you run your stock up against it.
Stick with half inch shank bits, and Freud bits are very good and available at Home Depot.
One other item you might consider is a dust collection setup for your router. The picture below shows a bucket with a Dust Deputy cyclone separator, linked to a shop vac. The bucket collects most of the sawdust so you don't clog the shop vac filter. I'd go for at least a 14 gallon shop vac, and you might find one used in a thrift shop. That dust collection will save your lungs, that with a dust mask is very important. And, you will find sawdust gets under your workpiece. Keep brushing it away or it will lift your piece up a bit and ruin the alighment on assembly.
I also added a picture of the type table and fence I started with, vs a shop made fence with dust collection.
You could also check second hand stores for a wood table or dresser and use that for your router table.
OK, here are the pictures, including a fence. As always, they have jumped out of order, but you can tell which is which.
The more I do, the less I accomplish.
