Tiger Direct is ok, but you need to be VERY CAREFUL when purchasing equipment from them. Often it is a refurbished item, and it may not be clearly stated that it is not new but refurbished.
Newegg has industry leading customer service. Often you can find good deals on most things there. Also, you may want to consider some of the deal a day sites like fat wallet
they have members around the country, and you will often know about deals as fast as they occur.
Me personally, I own a Lenovo laptop, and an Acer. Lenovo used to be an IBM subsidiary, but is now independent. They make reasonable laptops in the 500-1500 range.
Acer has really stepped up their game in the last 3 years as well. Once relegated to the bargain basement of computer hardware they have really emerged as a top of the business company.
Laptops, however are pretty much divided into simple catagories
1. intel vs AMD
2. Gaming or business
3. storage space needed
I think you will find most any NEW laptop today will be able to handle any thing your needs seem to dictate. Genealogy is not a tasking chore for a computer. You are using websites to trace family roots and ties to the past. It's not likely you will need massive graphics power for gaming. JPEG images are not huge but a laptop will come with at least 250 gigabytes of storage on the built in hard drive. You can consider a external hard drive as well so you can move from one PC to the next easily. Typical pricing on an external drive is under 100 dollars for a 1tb hard drive, and I have seen 2tb drives on sale for 99 recently.
You, yes YOU! STAND STILL WITH IT! How can you have any pudding if you don't eat your meat?
