Suggestions on what to buy at inventables

So I won a $50 gift card to inventables. Any suggestions on what to buy? Everything in their inventory is a option.

Bits, extra belts

i could tell you what i need but i guess that does not count.

Makes sense. I have the newest xcarve with the xcontroller. are these upgrades available from inventables? I could def go for taller end plates.

I guess im looking fr make makes the most sense to buy from this site. Materials and bits I’ve found elsewhere unless there is a really good one they have that i am missing.
