I'm not familiar with Coghill's version. There's also an $8.00 version at https://www.amazon.com/dp/B006X2AZHC, I can't tell the difference in the preview.
The version I really like is worth getting even at $10, if you have any long-term interest in Chaucer: https://www.amazon.com/dp/B00B13DK7K -- it has the original with stresses indicated (often not obvious) and great easy to use glosses. An exemplary ebook.
