Great offer with the pdf/printed version combo. WHile I wait for the printed version I've had a read through my pdf copy and really like the inclusion of the variant weaponry and armour materials. Many of them are familiar from older editions and its great to see them given the 5e update.
While its a shame I can't inlcude them in my Adventurers League games I'm totally going to be adding them into my home games.
Many of the items while not being over powerful have flavourful abilities and bonuses which I find much more useful and entertaining. The few that immediately spring to mind are the Swashbuckler's Leathers (as I play a swashbuckler), the Arcane Thieves Tools (which I can already imagine being really useful for Arcane Tricksters), and the Wand of Incontinence (just because I think its hilarious to make your opponent wet himself).
