If you were given $1000 dollars

I've been mainly dealing with $5-20 dollar items from thrift and reselling them on NZ's version of eBay. But if I was to sell my phone for approx $1000 dollars would there be any bigger ticket items worth trying to flip? or just buy A LOT of the $5-20 items?

Also, within your niche, do you have place limits on yourself to know when something may be too expensive/too much risk? Thanks!
