I can't answer about the price difference between two similar bikes. But answer this: Since you like the Vita that much, if you bought the Giant, would you be wishing you had the Vita? Are the rides similar?That is a big price difference, and if you really can't afford the Vita, then I wouldn't push it. But if it is something you can afford, even if it's more than you wanted to spend, it would be a shame to just "settle" when your heart is on something else. How's that for enabling?
