Yes, choosing a Latin text to work with is an ongoing consideration. The text used by Perseus would be easiest, but I'm not sure I want to be tied to their licensing agreement (however free and easy). I believe they use William Ellery Leonard's correction of the text, which should be Public Domain, but since revision is ongoing for all Perseus texts that presents a problem.

Quite so! I'm tempted to go back to Munro, and use his Revised 4th Edition. (1900) If I can find it...
