any seasoned scrappers out there...???

could use some advice... my dear hubby gave me some dinero to do a bit of shopping to increase my scrap booking materilas. I have paper, pens and glue, a few scissors and a few stamps. I know I should probably have some kind of paper cutter, not sure what kind though. Any ideas on what else I shoud get?? Help me spend some money...LOL!!! Any and all advice would be greatly appreciated!

*Edited* Thank you Darcy and April...I am ready to go shopping!!! :)
