Now that you have The Spider pulp ring premium on your finger, how about an Operator #5 ring?
A seller by the handle of wu_wei_dragon has a nice example of the ring for sale on eBay for a buck under $10,000. (Shipping is free.)
Update: The listing was ended on Feb. 12 with a $5,500 price. The ring has been re-listed for a $4,400 buy-it-now price, or $4,000 opening bid, ending Feb. 19.
