Ok, I'll start playing it over the weekend. Also, there's no point in posting high-score tables for every score. Just post an in-game picture if you want to ilustrate something -- like a particularly tough spot for example.
About the Hori stick, now. It costs about 4,000 yen, depending on the store. I think the cheapest I've seen it is 3,800.
A used Saturn goes for anywhere betweem 5,000 and 10,000 yen, depending on the condition, and if it comes with a box, manuals etc. Check out this auction for example:

The Saturn is used, but in "like new" condition, and everything is included. Auction starts at 9.800 yen, and the Buy-It-Now price is 19,800. It ends in 4 days. If you want me to bid on it tell my your maximum bid and I will try to get it for you. (Of course then you'd have to send me the money within 3-4 days after the auction ends. You can deposit it into my NovaBank account if you want to.)
A new Saturn is quite a bit more expensive. I've seen them go in auctions for 20,000 to 40,000.
