Are they worth buying after all this time, and what is good or bad about them.
I would just to read all the stories again. Was fun to read them.

Are there any specific issues or stories you'd recommend to others?
Not that I can recall offhand, been a long time since I have read them and haven't got the time to.

How do they compare to the current era of Transformers comics?
Hard to compare them. I like both the old ones and the new ones.
