Well I like the stuff that Cisco Kits has to offer, unforunatly a lot of the dual router kits are sold out. There are some other kits but at a much higher cost, I won't mind going the extra mile to spend more cash if its worth it. I do intend on heading towards a CCNP after I get my CCNA.
I see this kit right here
http://www.ciscokits.com/cube/index.php?act=viewProd&productId=19, it has two 2620's that look pretty nice and "a ISDN module so you can run your ISDN commands and a back to back cable to simulate your WAN connection." Is this something you guys would recommend? It looks like good practice for frame relay perhaps. Unfortunatly there is no switch included with this bundle (can someone hook me up with a good deal???

)
There are other dual 2503 router kits for a lower price, but would you people recommend 2620's or 2503's for going beyond a CCNA?
