I ran across these guys on eBay. They're selling Dell T5810 workstations with "low end configuration" (though more than adequate for trading) for very low prices* and including 1 year warranty (optional 3-yr for additional $40). Bought one myself. They sent me the wrong one but quickly "made things right". Can't beat that! They have >100,000+ transactions with 99+% feedback. Look for them on eBay or ... www.Reviveit.io FWIW... *If you buy one of these quality machines for stupidly low price, you owe me a beer and a burrito!
