davidcyclebackOn occasion in the past I have spent too much on expensive single items.  
These days, I do not spend a lot on a single item.  I'll spend a $1,000 or more on a group lot (eg 70 autographed baseballs), but I can't even remember when I spent $1,000 or more on a single item.  Which means it's no great deal if you overspend on a $100 or $200 or $50 item.  
As a collector, and even as an eBay reseller, I often get more enjoyent out of a $20 item than a $1,000.  Heck, I enjoy looking at other peoples' collections and having the owner tell me about the unfamiliar material.  Enjoyable learning something new and it doesn't cost me a penny.
