Give it a go. I've tried it and it's not too difficult. The previous advice about dust on the neg is entirely appropriate; the unsharp mask will accentuate these somewhat. If you've got a lightbox, then the whole registration process is made that much easier. Personally, I used Maco 'genius' sheet film (great name isn't it!) and devved it in dilute exhausted Neutol. I got good results.
