To the OP, it all depends on what you mean by less costly. I have both my MCSE and CCNA and I would say between study guides, labs and tests they came to about the same in price for me to study for on my own.
The MCSE is 7 tests and with most books you buy for your MCSE you can get a free trial of server 2003. I would build 1 powerful computer and run a flavor of virtualization software on it (Microsoft Virtual PC/Server or VMWare Server) 3 windows server 2003 virtual machines and 2 XP (or Vista depending on your OS test) virtual machines
The CCNA is 2 tests, but you will need to build your own lab, now people have said that you can use Boson NetSim, SemSim, or GNS3 (free open source Cisco Simulator) but you need to have smartnet inorder to download valid IOS images. Personally you can get all you need from e-bay.
My CCNA lab was 1 2500 series router, 3x 2600 series routers, and 3x 2900 series switches, and 3 back to back cables to connect them. and if you progress with your Cisco studies (CCNP and CCIE) you can reuse most of the equipment that you get into a different lab. Plus if you have no Cisco experience, it doesn't hurt to see what a router/switch looks like, how it operates and so on. With Cisco study guides, Cisco Press is your friend. The best written certification manuals/study guides around.
These are just my opinions, and if you want any help or have any more questions don't hesitate in asking.
