Is Keen Engineering worth buying?
As singles, the cards in Keen Engineering are worth about €51.72 / $48.08. 54% of that sits in ten cards, led by Scrawling Crawler and Misleading Signpost, so the deck's value depends heavily on those few. If you can buy the sealed deck for less than its singles value, you're getting the cards cheaper than buying them one by one.
Value isn't the whole story, though. If you already own the staples, a precon adds less to your collection than its price tag suggests. What matters is how many of these 100 cards would be new to you, and what those are worth.
