Cisco Catalyst 3550-24 SMI to EMI conversion

Hi, I'm planning to buy a 3550 for my CCIE study lab & need to know if ANY Cisco Catalyst 3550-24 SMI can be converted to EMI by changing the IOS image or has Cisco created some restrictions whereby these can only be upgraded on certain models and not on certain ones.

I know of people who have upgraded their 3550 SMI switches to EMI images, but have recently heard that Cisco was planning to change something whereby this is no longer possible.

Also, please also advise me on Catalyst 3750 switches. Are these going to be replacing the 3550s in the lab & will 3550s remain suitable enough for lab practice or will there be features that are not available in the 3550s but present in the 3750s that will make investment in 3550s not very advisable?

Request a clarification.

Thanks! SB
