Any hardware differences in last 9 months?

[Counterfeit]

Hello all, I am in the market for an HTC TP2 but will be not be buying from Sprint. I am doing this so I do not waste my upgrade. There are a couple of Craigslist entries not too far from my home (I don't live near any big cities really) and one of those is for a 9 month old $100 TP2. Here is the listing:

I was just wondering if there were any hardware or other differences between 9 months ago and now for the TP2? I wanted to get a brand new/pretty much new one for around $175 if possible (one listing for such price, but it may be sold already) but if I cannot, then I thought this may be a feasible option.

All thoughts are appreciated.
