Are you like I was, getting frustrated when browsing flea markets, garage sales, thrift shops, etc. and not knowing whether or not you are paying too much? I can't tell you how many things are gathering dust because I bought them to sell on eBay and they didn't sell. So, what I did was get a PDA, which is a hand held internet capable device. Now if I am interested in investing in something, I can do it with confidence. All I do is look it up on eBay and see if there is a demand for the item. I look at bids, how many people viewed the item, and what it is selling for in eBay stores. For instance, I bought a Hull vase for $75.00 at a thrift shop. The book value of this piece was $300, and I thought for sure I was going to make at least $75 on it. Well, is worth about $50 on eBay. The market had obviously softened. If I had my PDA I would not have bought it. Although, I might be able to sell it at a flea market I'm hoping. My PDA was $400 and is about $70 per month. That includes unlimited downloads, and doubles as a cell phone as well. It's about the same size as a regular cell! So, That is my advice to you.
