Seeking Advice

Hello,

I am in the process of learning computer forensics. I have been in the info security world for 10 years and very familiar with both windows and UNIX, networking and security in general. I have taken the SANS Forensics course and spent what time I can learning different free forensic tools, and forensic concepts. My goal is to get a new job at some point with a company doing full time forensics. My question is this. I have a budget that I have put forth to spend (invest in myself) for education. I am thinking of buying a copy of FTK (full version) and learning the tool inside and out hoping that knowing this tool, which is probably used more in shops rather than free tools such as TSK and autopsy etc. Is this a good investment? For those of you doing forensics for companies are you using FTK, if so how much compared to other tools. How do you think it would help if I showed that besides everything else that I have learned about forensics I also have in-depth knowledge of FTK. Again, is it worth the investment?

Any help would be appreciated.

Thanks,

Alan
