Hi, dan

The only built-in port on 3640 router is the console/aux port. A bare 3640 router doesn't have any lan or serial port that you can use to practice on the lab. You will need to buy 1 NM-1E2W or NM-1FE2W and other 2 wic-1T cards. This make your 3640 router have 1 lan port and 2 serial port that will conform the basic needs for most labs. NM-1E2W is much cheaper but have some limitations you should notice:

1.The ethernet port on NM-1E2W supports dot1Q trunking only. It doesn't support isl trunking which sometimes you will be asked to do on the lab. In that case, you will need a NM-1FE2W or a NM-1FE-TX instead.

2.WIC-2T card is not support on NM-1E2W. So, if you have any WIC-2T in hand, you will need a NM-1FE2W to make your cards to work.

3640 can run 12.4 advance enterprise code with the maximum falsh/memory of 32/128 MB. This is quite enough for most of the labs.

As for the 2600 routers which have the same capability to run 12.4 code and should not be too pricy, I would recommend the 2651 router (which has two FE ports) or the 2610xm (which has only one FE port). And even better, you can run 12.4T code on them if you max out the memory to 32/128.
