I am just starting into studying for CCNP and I have decided to build a home lab which can hopefully be expanded on for CCIE if/when I get that far. I know I can do routing through GNS3 but I would rather get the actual equipment and build the home lab if it is anyway financially possible.
I managed to pick up a couple of 3560s fairly cheaply which I'm hoping will be staying on the CCIE equipment list for the next year or two? I already have a 2950 so I was thinking of just buying a second 2950 and using those for CCNP SWITCH and CCNP TSHOOT and I can replace the 2950s with 3550s if/when I get to study for CCIE.
The routing I am unsure of, what routers should I be looking at that can possibly be used for CCIE aswell? I have spotted a 2522 and a 2691 at reasonable prices and someone is selling some 2600(standard, not XM) routers cheap also.
How many routers do I need and what types?
I'd appreciate some advice on what the optimum build would be keeping the CCIE in mind also but not going nuts on my bank balance at the same time.

Thanks in advance for the advice, i read through the stickies but those labs seem to be a few years old so I said I'd better check here instead.
