User blog:The Lord of Minas Morgul/Should I Get Fastcraft?

No, I haven't gotten fastcraft yet. Yes, I know I should get it. In fact, I intended on getting it a couple months ago, but I had second thoughts when I read this:

"There may be bugs and the code is somewhat experimental, make backups of your world save while using it."-Excerpted from the fastcraft thread on industrial craft forums.

Have you guys had any problems like that? If someone says yes, Should I just get it and keep making backups in a lengthy process, or should I just not get it? If someone says no, I'll obviously get it, seeing as to how it would be problem-free. Thanks in advance!
