if you want to monetize your points straight away, I'd recommend some lower end prizes, namely Bewitching Sorcerers Bonnet and Thieves Hood. They're buyable, so you can just toss them in your shop, and are ETS while still getting you quite some bucks for your points. I'd def. not go for the petpets as they're really HTS, so meh. If you want to bother with unbuyables, go for the background or foreground - stay away from the BD weapons as A Shovel is super situational and even that not overwhelming and accordingly HTS and the only other good one is Rejuvenating Jar of Brains, but the market is flooded with those, so they don't net that many NP for the points they cost
